This document provides information about acceleration due to gravity. It defines acceleration due to gravity as the acceleration of a freely falling body due to the gravitational force of attraction exerted by the Earth. It is denoted by 'g' and is independent of the mass of the falling body. The value of 'g' depends on the distance from the center of the Earth and varies from 9.83 m/s^2 at the poles to 9.79 m/s^2 at the equator. 'g' decreases with increasing distance from the Earth's surface and is zero at the Earth's center. The value of 'g' also varies for other planets depending on their radius and mass.

This document discusses the universal law of gravitation and its implications. It can be summarized as follows:
1) The universal law of gravitation states that the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
2) This law explains phenomena like the orbit of planets around the sun and the moon around Earth. It also explains why objects fall with an acceleration of 9.8 m/s^2 on Earth.
3) The weight of an object, which is the gravitational force exerted by Earth, differs on other celestial bodies due to differences in their masses and radii. Calculations show an object's weight on

The document discusses Newton's universal law of gravitation. It explains that gravity produces an attractive force between bodies that depends on their masses and the distance between their centers. It also describes how orbital motion occurs when the speed of an object is great enough that the curvature of the Earth causes the object to fall into orbit rather than hitting the surface. Additionally, it discusses how astronauts can jump higher on the moon due to its weaker gravitational pull compared to Earth.

1) Gravity is the force of attraction between two masses, and it causes weight, which is the downward force on objects. Mass stays the same anywhere, while weight depends on location.
2) The weight of an object can be calculated using the formula: Weight = Mass x Gravitational Field Strength. On Earth, gravitational field strength is about 10 N/kg.
3) Gravity decreases with distance from a large mass like Earth or the Sun. Planets further from the Sun move slower and have longer orbits. Satellites orbit Earth in different patterns depending on their purpose.

Gravity for Elementary and Middle students (Teach)
Gravity is a force that pulls all objects towards one another. The more mass an object has, the stronger its gravitational pull. While it appears lighter objects fall slower on Earth, this is due to air resistance, not differences in mass - in a vacuum all objects fall at the same rate. The amount of gravity and weight experienced varies on different planets depending on their mass.
universal gravitation
This document provides an overview of Isaac Newton's theory of universal gravitation. It discusses how Newton realized that the force causing apples to fall is the same force that causes the moon to orbit the Earth. The document then presents Newton's universal law of gravitation, which states that the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. It also explains key concepts like gravitational fields and how gravity works inside planets and for artificial satellites and black holes.
Gravitation
- Gravitation is a phenomenon where objects are attracted toward Earth.
- Sir Isaac Newton first proposed the idea of universal gravitation after observing an apple fall from a tree.
- Gravitation is important because it causes planets to orbit the sun, tides, and binds objects to Earth.
- The motion of the moon around Earth is due to the centripetal force of Earth's gravitational attraction.
- While objects attract Earth due to gravitation, we don't see movement because Earth's mass is much greater.
- An object in free fall is only influenced by gravitational force toward Earth.

gravitation
1. Gravitation is the force of attraction between two objects due to their masses. The universal law of gravitation states that the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
2. When an object falls towards the earth due to gravitational attraction, it is undergoing free fall. The acceleration during free fall is called acceleration due to gravity (g), which is about 9.8 m/s^2 on earth.
3. Archimedes' principle states that when an object is immersed in a fluid, it experiences an upward buoyant force equal to the weight of the fluid displaced by the object. This determines whether
Phys111 lecture13
1) Newton's universal law of gravitation states that every object in the universe attracts every other object with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.
2) Orbital motion, like the moon orbiting the Earth, is in a state of constant free fall under the force of gravity.
3) For a satellite or moon to maintain a stable, circular orbit around a planet, it requires a precise centripetal acceleration provided by the planet's gravitational pull.
Gravitation
1. Gravitation is a natural phenomenon that causes physical bodies to attract each other. Newton studied the motion of the moon around Earth and determined that the same laws govern the motion of objects on Earth and in the sky.
2. Newton calculated that the acceleration due to gravity on Earth is 9.8 m/s^2. Gravitation explains the orbits of planets around the Sun and the tides caused by the gravitational attraction between Earth and the Moon.
3. The value of the gravitational acceleration, g, can be used to predict the orbits and time periods of satellites around Earth. Kepler's laws describe the elliptical orbits of planets around the Sun.
Gravitation class 9
This document summarizes key concepts about gravitation and motion. It explains Newton's law of universal gravitation, which states that gravitational force between objects is directly proportional to their masses and inversely proportional to the square of the distance between them. It also defines gravitational acceleration as about 9.8 m/s2 near Earth's surface. Additionally, it discusses centripetal force, weight versus mass, buoyancy, pressure, and Kepler's laws of planetary motion.
Gravitation (ppt)
The gravitational pull of the Sun on the Moon is greater than the pull of the Earth, but the Moon remains in orbit around the Earth because:
1) The Moon and Earth orbit around their common center of mass, which is closer to the Earth due to its greater mass.
2) The centripetal force keeping the Moon in its circular orbit is provided by the Earth's gravitational attraction of the Moon.
3) The center of mass of the Earth-Moon system and the Sun orbit around their common center of mass, which is closer to the Sun due to its overwhelming mass.
Gravitation
This is the NCERT CBSE syllabus ppt on the topic Gravitation. It will be helpful for students studying in that class and will enable them to understand better.
9 j gravity and space
1) Gravity is an attractive force that depends on the mass of objects and the distance between them. It affects anything with mass.
2) On Earth, gravitational field strength is 10N/kg. An object's weight is calculated by multiplying its mass by gravitational field strength. Some examples of weight calculations on Earth are provided.
3) When a rocket launches from Earth, the force needed to accelerate it decreases as it gains distance from Earth and loses mass by burning fuel, both of which decrease the gravitational force pulling it downwards.
Chapter 11 GRAVITATION
Newton's Universal Law of Gravitation describes the gravitational force between two masses. The force is directly proportional to the product of the masses and inversely proportional to the square of the distance between them. Kepler's Laws of Planetary Motion describe the motion of planets around the sun, including that their orbits are ellipses with the sun at one focus, they sweep out equal areas in equal times, and the squares of their orbital periods are proportional to the cubes of their distances from the sun. A satellite stays in orbit around a planet when its centripetal force due to its velocity balances the gravitational force exerted by the planet.
Gravitation
The document discusses Newton's law of universal gravitation. It defines key terms like gravitational field and explains Newton's observations that led to his formulation of the law. The law states that every object in the universe attracts every other object with a force proportional to the product of their masses and inversely proportional to the square of the distance between them. Examples are given of calculating gravitational forces between objects using the law. Lord Henry Cavendish experimentally determined the gravitational constant in Newton's law through measurements with a torsion balance apparatus.
GRAVITATION CLASS 11TH
This document provides an overview of key concepts in gravitation including: the definition of gravitation; Newton's law of universal gravitation; acceleration due to gravity and how it varies with height and depth; escape velocity; orbital velocity; gravitational potential; time period of satellites; Kepler's laws of planetary motion; and types of satellites. Key points covered include how gravity decreases with height but increases with depth below the Earth's surface, and definitions of geostationary, polar, and binding energy as they relate to satellites orbiting the Earth.
Gravity
Gravity is one of the four fundamental forces and describes the attraction between masses. Newton's law of universal gravitation provides an accurate approximation for calculating gravitational effects. Gravity causes acceleration at 9.81 m/s^2 at Earth's surface and is responsible for weight. Applications of gravity include its role in dynamics through Newton's laws of motion as well as in technologies like gravity chairs and skateboards.

This document discusses Kepler's laws of planetary motion and Newton's universal law of gravitation. It also describes how gravitational acceleration varies with altitude, depth, and latitude on Earth. Some key points covered include:
1) Kepler analyzed Tycho Brahe's planetary data and discovered three laws, including that planets orbit in ellipses with the Sun at one focus.
2) Newton's law states that the gravitational force between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them.
3) Gravitational acceleration decreases with altitude and depth from Earth's surface, and is lowest at the equator due to centrifugal effects.
Gravitation - Physics
This document discusses concepts related to gravitation and gravity. It begins with a brief history of gravity and Newton's law of gravitation. It then defines gravitation as the attractive force between any two objects with mass, and defines gravity as the gravitational force that occurs between Earth and other bodies. The key points are that gravitation is a universal force, while gravity specifically refers to the gravitational attraction of Earth. The document goes on to provide explanations and formulas for concepts like gravitational constant, acceleration due to gravity, mass vs weight, and center of gravity vs center of mass.
A2 gravitational field KYUEM Physics
Gravity is a mysterious force that attracts all objects with mass, even when far apart. Newton discovered that all objects accelerate towards Earth at 9.81 m/s2, and the moon accelerates towards Earth at 2.72 m/s2. Gravity is weak but exists between all objects, causing dust in space to come together to form stars and planets.

GR.ppt
General Relativity is Einstein's theory of gravitation that describes gravity as a result of the curvature of spacetime caused by the uneven distribution of mass/energy. It has been extensively tested and confirmed through observations of orbital precession, gravitational lensing, and gravitational redshift/time dilation. Black holes are a extreme prediction of GR where spacetime is so strongly curved that nothing, not even light, can escape once within the event horizon.

Philosophy
Paulo Freire was a Brazilian philosopher and the father of critical pedagogy who developed the concept of conscientization. Conscientization is the ability to critically perceive the causes of social, political, and economic oppression in order to take action against oppressive elements of society. It involves developing a deep understanding of the world that leads to freedom from oppression. Freire viewed education as a tool for liberation that should involve dialogue between students and teachers to develop a shared critical understanding of reality. His educational philosophy emphasized problem-posing education, dialogue, and using education to promote conscientization and liberation.

Limitations of educational psychology
1) Educational psychology deals with studying human behavior in educational situations, but faces several limitations.
2) Limitations include the unpredictable nature of human behavior, wide individual differences making it difficult to adopt strategies for all learners, and the gap between theoretical situations and practical classroom applications.
3) Additionally, psychological experiments are less reliable because children and educational environments are flexible and can influence behavior differently.

A chemical bond is an attraction between atoms that allows the formation of substances containing two or more atoms. The bond is caused by electrostatic forces of attraction, either between electrons and nuclei or due to dipole attraction. When metals bond to nonmetals, electrons from the metal atoms are transferred to the nonmetal atoms, resulting in the metal atoms becoming positively charged ions and the nonmetal atoms becoming negatively charged ions.
