Force is a push or pull that causes changes to an object's movement, shape, or direction. It can cause changes in movement by pushing or pulling an object, changes in shape by stretching or squeezing, and changes in direction by applying force to change the object's path. Common types of force include friction, gravity, and magnetism. Friction is the force between surfaces in contact. Gravity is the force that attracts objects toward each other. Magnetism is the force that magnets exert to attract iron and steel objects.

Earthquakes are caused by the sudden release of built-up stress in the Earth's crust that generates seismic waves. There are three main types of faults that cause earthquakes: strike-slip, thrust, and normal. Tectonic plates pushing against each other cause stress that results in either plastic or elastic deformation of rocks; elastic deformation leads to a breaking point where stored energy is suddenly released as seismic waves. The focus is where the slip occurs underground, while the epicenter is on the surface directly above. Modern seismographs can detect and measure seismic waves to provide information about earthquakes.
Intensity
The document describes the Philippine Institute of Volcanology and Seismology (PHILVOLCS) earthquake intensity scale, which ranks earthquakes from intensity level 1 to 10 based on their observed effects on people, structures, and the earth's surface. Intensity 7 earthquakes are described as being destructive and causing cracks in structures, while an intensity 10 earthquake would be completely devastating and destroy virtually all human infrastructure. The intensity of an earthquake typically lessens as the distance from the earthquake's focus increases.

Faults and forces 9.1
Forces inside the Earth put stress on rocks, causing faults where rocks bend and break along surfaces. There are three main types of faults: normal faults where tension pulls rocks apart, reverse faults where rocks are forced up over other rocks, and strike-slip faults where rocks slide past each other horizontally. Earthquakes occur when built-up stress causes rocks along faults to break and release vibrations at the surface.
4 4 Deformation
The document discusses how stress deforms and shapes the Earth's crust through folding, faulting, and other tectonic processes. It describes the three main types of folds and faults, and how convergent, divergent, and strike-slip boundaries each produce different styles of deformation. Various mountain-building processes are also summarized, including folded mountains, fault-block mountains, and volcanic mountains formed at plate boundaries.
Deformation of Crust
The document discusses the deformation of rock crust through various tectonic processes. It defines deformation as the process by which crust is deformed along plate margins, producing geologic structures like folds, faults, joints and foliation. It describes how different rock types deform under stress through either ductile or brittle deformation. The key types of deformation discussed are folding, where layers of rock are bent, and faulting, where connected blocks of rock are displaced along a fracture plane. Common fold types include anticlines, synclines and monoclines. Fault types include normal, reverse, strike-slip and oblique-slip faults.
EARTHQUAKES AND FAULTS
The document discusses earthquakes and how they occur. It explains that earthquakes are caused by sudden movement along faults in the Earth's crust due to a build up of stress. There are three main types of faults - normal, reverse, and strike-slip - each forming in a different way due to tension or compression in the crust. When friction along a fault is overcome, the fault will slip and move, causing seismic waves that produce shaking during an earthquake. The intensity of shaking and damage decreases further from the earthquake's epicenter.
Anticlines and synclines
Anticlines are folds where rock layers slope upwards on both sides of a central low point, forming a hill or mountain range, while synclines are folds where rock layers slope downwards on both sides of a central crest, forming a valley or the side of a cliff. Both anticlines and synclines form due to compression from plate tectonic forces.

Earthquakes
An earthquake is caused by the sudden movement of tectonic plates along fault lines in the earth's crust. This movement sends out shock waves that can damage structures and alter the earth's surface by causing landslides, tsunamis, and volcanic eruptions. The location below the surface where the earthquake starts is called the hypocenter, while the epicenter is the location directly above on the surface. Earthquakes occur when built-up pressure causes rocks along fault lines to suddenly break. The most devastating earthquakes in history include the 1556 Shaanxi earthquake in China that killed over 830,000 people and the 1976 Tangshan earthquake in China that killed between 240,000 and 655,000 people.
How rocks behave under different types of stress
This document discusses how rocks behave under different types of stress. It explains that rocks undergo deformation and strain when subjected to tensional, compressional, or shear stresses. The document outlines the different stages of rock deformation, from elastic to ductile to fracture, and factors like temperature, confining pressure, and composition that influence the deformation process. It also describes geological structures like joints, faults, folds, anticlines and synclines that form from rock deformation.
Behaviors of Rocks Under Stress and Pressure
Rock structure documents tectonic movements beneath the Earth's surface that deform rocks through compression, tension, and shearing forces. Compressional forces push rock layers together, causing folding and faulting. Tensional forces pull rock layers apart, forming basins and rift valleys. Shearing forces cause vertical or horizontal displacement along faults. These tectonic forces shape the Earth's crust over geological time.

Diastrophism refers to the dynamic forces that generally act to elevate the earth's surface, such as uplift, subsidence, and thrusting. There are several theories that attempt to explain diastrophism, including isostasy, contraction theory, and convection theory. The effects of diastrophism can be seen in the structural features of rocks, including folding patterns like anticlines and synclines, joints, faults, and tilting or bending of strata.
Force
Force is defined as a push or pull that can change an object's motion or state of being. There are different types of forces, including contact forces which require touching between objects and non-contact forces like magnetism and gravity which act over a distance. Forces are measured in units like newtons and can be measured using tools such as spring scales. Common examples of forces include lifting, kicking, and pulling or pushing objects.

Causes of earthquakes
Earthquakes occur due to forces within the Earth's structure. The planet's crust is broken into tectonic plates that float on the mantle, sometimes getting stuck and building pressure at the seams. When plates suddenly slip past each other, it causes the ground to shake and structures to fall. Most quakes happen along areas in the Pacific Ocean called the Ring of Fire. Beyond initial shaking, earthquakes can lead to dangerous secondary events like tsunamis, fires, and landslides that claim thousands of lives annually.
F05 diastrophism
Diastrophism refers to deformation of the Earth's crust due to tectonic stress. It results in folding and faulting of rock layers. Folding occurs when compressional stress causes rocks to buckle, forming arches (anticlines) and sinks (synclines). Faulting occurs when rock is strained beyond its ability to remain intact, resulting in fracturing and displacement along a fault plane. The three main types of faults are normal, reverse, and strike-slip (transcurrent). Normal faults result from extensional stress, reverse from compressional, and strike-slip involve horizontal movement with no vertical displacement.

Force and pressure
Force can be a push or a pull that requires two objects and can move or change the shape of an object. There are different types of forces including contact forces like muscular and frictional forces, and non-contact forces like magnetic, electrostatic, and gravitational forces. Force can change an object's motion by putting it into a state of rest or motion, and can change the shape of an object. Contact forces require physical touch while non-contact forces act over a distance. Pressure is defined as the force applied per unit area, and pressure from liquids, gases, and the atmosphere can be exerted on surfaces and inside our bodies.

Forces and movements
This document summarizes three different types of forces: contact forces, magnetic forces, and gravity forces. It provides examples of each force and how it interacts with objects. Contact forces require touching objects and can push or pull objects to move or change their shape. Magnetic forces do not require contact and can attract or repel ferromagnetic materials using magnets. Gravity forces also do not require contact and attract all objects with mass toward the center of the Earth or other astronomical bodies.
Forces
Forces only exist as a result of an interaction between two objects. Contact forces can change the shape of objects or break them depending on the amount of force applied and the material. Magnetic forces are non-contact forces created by magnets that attract certain metals and allow magnets to move objects without touching them. Gravity is also a non-contact force that pulls all objects toward the center of the Earth, causing things to stay on the ground and fall back down.
ENERGY AND CHANGE GRADE 9.pptx
This document discusses different types of forces. It defines a force as a push or pull exerted on an object. There are two main types of forces: contact forces which require touching, like friction and tension, and non-contact or field forces like gravity and magnetism which act over a distance. Gravitational force is exerted by all masses and depends on their masses and the distance between them. Magnetic force occurs between magnetic poles, with opposite poles attracting and like poles repelling. Electrostatic force is exhibited by charged objects, with opposite charges attracting and like charges repelling.

Forces and motion
Forces can make objects move, stop, or change shape. There are different types of forces including gravity, electric force, magnetic force, and friction. Forces can also distort objects temporarily or permanently. Forces affect motion by making things move, stopping moving objects, and changing the direction of moving objects. Machines are devices that use or convert energy. They can be powered by human energy, natural energy sources like water or wind, or electricity. Machines produce various types of movement or thermal effects and can process information.
Friction notes.PDF
Friction is the force that opposes the relative motion between two surfaces in contact. It is caused by either the interlocking of the irregular surfaces where they meet, or the electrostatic attraction between the atoms of the two surfaces. Static friction is the force needed to initially move an object from rest, while sliding or kinetic friction is the lesser force needed to keep it moving. Friction has both advantages, like enabling walking and braking, and disadvantages, such as wearing down materials. Methods to increase friction include adding treads or spikes, while decreasing friction can be achieved through lubrication or making surfaces smoother and rounder.
Forces.pptx
The document summarizes different types of forces:
1) Gravitational force causes objects on Earth to fall towards the ground and water to flow downwards.
2) Muscular force allows humans and animals to exert physical strength to change an object's motion, like pushing a car or pulling a cart.
3) Friction force resists the motion of objects in contact with each other. Contact forces require physical touching, while non-contact forces like magnetic and gravitational forces act without touching.

Other topics covered include monsoons, trade winds, the Intertropical Convergence Zone (ITCZ), ozone formation and depletion, and the greenhouse effect.
Responsible parenthood
The document discusses the Responsible Parenthood and Reproductive Health Act of 2012 in the Philippines, which guarantees universal access to contraception, fertility control, sex education, and maternal care. It mandates the government to promote all effective and legal family planning methods. The bill also requires reproductive health education in schools and guarantees reproductive healthcare for female employees. It aims to promote responsible parenthood through a multi-dimensional approach integrated into anti-poverty programs.
The atmosphere
The document discusses the layers of Earth's atmosphere. It is divided into five main layers from lowest to highest:
1) The troposphere, extending up to 9-16 km, contains weather patterns and decreases in temperature with altitude.
2) The stratosphere, up to 50 km high, contains the ozone layer and has a temperature that initially increases with altitude.
3) The mesosphere, up to 85 km high, has a sudden temperature increase then decrease with altitude and contains ionized layers.
4) The thermosphere, 80-640 km high, has extremely high temperatures over 1000°C and contains the ionosphere responsible for reflecting radio waves.
5) The exosphere, over
Gravity
The document discusses the force of gravity and its effects. It explains that gravity is a downward pulling force that attracts all objects on Earth toward its center. It causes things thrown up to fall back down, and makes downward movement faster than upward movement. Gravity is responsible for many phenomena we observe, such as leaves falling from trees, objects slipping from our hands, and kites falling when the wind stops blowing. It establishes our weight and keeps us and everything on Earth from floating off into space.
Maternal health concerns
This document discusses maternal health concerns before, during, and after pregnancy. Before pregnancy, women should see their doctor to discuss any existing health problems and how treatment may need to be adjusted. During pregnancy, women may experience a range of symptoms from mild discomforts to severe illnesses. Common health conditions experienced during pregnancy include anemia, UTIs, gestational diabetes, and hypertension. After pregnancy, women can experience postpartum depression caused by hormonal changes after childbirth. Proper prenatal and postnatal care is important for both mother and baby's health.
Energy
Most activities involve energy in different forms. Sound, light, heat, and chemical/mechanical energies are used from waking up until moving around. Forces like gravity, wind, water, electricity, and magnetism can push or pull objects to cause motion. Motion is the change in position of an object due to force. Forces can make objects move, change their speed and direction of movement, stretch or compress, or cause up and down motion through balanced or unbalanced opposing forces.
Heat energy
The document discusses heat energy and its effects on the human body. It explains that exposure to the sun's heat energy can cause sweating, thirst, reddening of the skin, and smelling musky. It then provides tips for protecting against excessive heat, such as avoiding direct sun exposure especially from 10am-2pm, drinking plenty of water, wearing loose cotton clothes, and staying alert for signs of heat illness like dizziness or fainting.
Friction
Forces can cause objects at rest to move or change an object's motion. There are two main types of forces - contact forces that require touching and non-contact forces like gravity. Friction is a contact force that resists the movement of objects in contact with each other. The document discusses the different types of friction like static, sliding, and rolling friction and how friction affects motion. It also describes ways to reduce friction using lubricants and wheels and ways to increase friction using rough surfaces. Safety measures around friction to prevent accidents are mentioned.
Dating, courtship, and marriage
This document discusses the topics of dating, courtship, and marriage. It defines infatuation and love, and notes that dating is a form of courtship where couples engage in social activities together. There are different types of dates like standard, double, and group dates. Dating is important as it allows couples to develop affection, strengthen their relationship, get to know each other's character, and have fun. Courtship precedes engagement and allows couples time to understand one another. Engagement is a period where couples ensure they are ready for lifelong companionship before marrying, which is a permanent union between a man and woman. Factors like maturity, commitment, and character are important to consider when choosing a lifetime partner for a
Periodic table
The document summarizes the key people involved in the discovery and development of the periodic table of elements. It discusses Johann Dobereiner who discovered triads of elements, de Chancourtois who arranged elements in a helix, Newlands who proposed periodicity based on atomic mass, and Mendeleev who created one of the first recognizable periodic tables. It also mentions the contributions of Meyer, Ramsay, Moseley, and Seaborg in refining the table and adding new elements. The periodic table organizes elements based on electron configuration in their outermost shells and exhibits trends in properties from atomic radius to metallic character across the table.
Kinematic equations
The document discusses kinematic equations that describe uniformly accelerated motion. It provides the equations for final velocity, displacement, and initial and final velocities as functions of acceleration, time, and initial velocity or displacement. Examples are included to demonstrate solving for final velocity and displacement given values for acceleration, time, and initial velocity. The kinematic equations can be used to analyze motion under constant acceleration.
Velocity
Velocity is defined as the rate of change of an object's position over time, taking into account both speed and direction, and can be calculated using the formula that average velocity equals displacement over time. The document provides examples of calculating average velocity and discusses how velocity differs from speed by incorporating direction. It also defines acceleration as the change in velocity over a time interval and provides examples of calculating acceleration from changes in speed or direction over time.
Teenage concerns
This document discusses several key issues regarding teenage sexual health. It notes that adolescence is a formative time when habits are learned. Some of the most important issues are physical body changes during puberty, increased interest in sex due to hormones, and the need for comprehensive sex education about risks and consequences. Teenagers are exposed to sexual topics from many sources and need guidance on their values. The document outlines additional challenges such as dating pressure, risks of teenage pregnancy, importance of abstinence or safe sex education, and sexually transmitted diseases.
Sound energy
Sound is energy produced by vibrations traveling through matter such as air. Vibrations cause the surrounding air to produce sound waves that transmit the sound outward from its source. When these waves reach the ears, the brain processes the messages as sound. Sound travels faster through solids than liquids or gases due to the density of the medium. It also travels much slower than light, explaining why thunder is heard after lightning is seen. Protection from loud noises that can damage hearing includes avoiding very close or prolonged exposure to sounds and wearing ear protection during noisy activities.
Velocity
Velocity is defined as the rate of change of an object's position with respect to time and includes both magnitude (speed) and direction. It can be calculated using the formula: Average velocity = Displacement / Time. In the example, a girl travels 8 km in 15 minutes (0.25 hours) to get to school, so her average velocity is 32 km/h. Acceleration is the change in velocity over a time interval and is calculated as: Acceleration = Change in Velocity / Time Interval. It is a measure of how quickly an object's velocity changes. Both speed and direction must change for an object to be accelerating.
Mangrove swamps
Mangroves are woody plants that grow in coastal saline waters and muddy soils between land and sea in tropical and subtropical regions. They have complex root systems adapted for survival in wet, oxygen-poor conditions. Mangrove swamps support rich biodiversity and provide important ecosystem services like coastal protection, sediment stabilization, and nursery habitats for marine life. However, mangroves are threatened by habitat loss from aquaculture, development, pollution, and overharvesting of resources. Conservation efforts aim to protect remaining mangrove areas and restore degraded ecosystems.
Electron configuration
This document discusses the electron distribution in orbitals and sublevels across the first four principal energy levels. It provides the number of orbitals and electrons in each sublevel (s, p, d, f) as well as the total electrons per principal energy level. The first level contains 2 electrons in the s orbital. Each subsequent level adds new sublevels with increasing numbers of orbitals and electrons as you move further from the atomic nucleus.

Force
- 1. FORCE
- 2. WHAT IS FORCE? Force is a push or pull that acts on n object due to its interaction with another object. It is applied on an object to cause changes – movement, shape, or the direction it is moving.
- 3. Effects of Force Changes in Movement Changes in Shape Changes in Direction
- 4. Changes in Movement Pushing (moving an object away from you) and pulling (moving an object towards you) something makes it move Ex: - Dribbling a ball - Moving a swing - Bringing a schoolbag close to you
- 5. Changes in Shape Ex: - Stretching a rubber band - Squeezing dishwashing sponge - Molding clay
- 6. Changes in Direction Different objects react different by changing the direction when force is applied. Ex: - Rolling a ball on the floor, then step on it, what do you think will happen to it? What force will you apply to stop it from roling?
- 7. Types of Force that affects the direction/movement of an object: Friction Gravity Gravitational force
- 8. FRICTION force exerted by a surface when something comes in contact with. It is the reason why you did not easily slip on the floor or ground when you step or walk on it. The friction is produced when the feet or shoes made in contact with the floor’s surface.
- 9. GRAVITY force that pulls two objects toward each other. It attracts people and objects to the ground. Causes: - you to come down when you jump. - the leaves of trees to fall off when wind blows - the ball thrown up in the air to come down
- 10. GRAVITATIONAL FORCE It is exerted by the moon and sun. its gravitational attraction to Earth, the moon tries to draw to its everything that is on the planet. Causes: tides or rising and falling of water in big bodies of water.
- 12. MAGNET – object that attracts other objects made of iron or steel, do not attract nonmagnetic materials like paper, cloth, glass, wood, and metals like aluminum and copper. - an invisible field that forces objects to react or an area un which a magnet exerts its force on certain objects. – ability to attract objects.
- 14. Kinds of Magnet Both kinds are made up of group of metals called ferromagnetic metals (include iron and nickel.
- 15. 1. Permanent Magnets retain their magnetism for a long time. made into different shapes, often formed into a U or bar shape. Ex: - Magnets that keep the refrigerators doors closed.
- 16. 2. Temporary Magnets lose their magnetism once they are no longer in contact within a strong magnetic field. Ex: - Steel paper clips exposed to permanent magnets
- 17. Law of Magnetism Force in a magnet is concentrated at its two ends, which are called poles. Force of attraction is strongest at the poles. North pole – end that points to the north part South pole – end part faces the south Same poles repel from each other, opposite poles attracts to each other.
