Half-lives can range widely from nanoseconds to billions of years.

Work energy power 2 reading assignment -revision 2 physics
This document discusses basic energy concepts including work, kinetic energy, potential energy, and the law of conservation of energy. It provides equations to calculate work (W=FΔx), kinetic energy (KE=1/2mv^2), and gravitational potential energy (GPE=mgh). Examples are given to demonstrate calculating energy transformations during events like a swing or skydiving fall. The key points are that energy cannot be created or destroyed, only transformed between kinetic and potential forms, and this transformation can be represented using energy bar charts.
Weight
The document discusses the differences between mass and weight. Mass is measured in kilograms and is a measure of the amount of matter in an object. Weight is measured in newtons and is the force exerted on an object by gravity. The strength of Earth's gravitational field is represented by "g" which equals 10 newtons per kilogram, meaning that a 3 kilogram object weighs 30 newtons on Earth. The Moon's gravitational pull is weaker than Earth's at 1.6 newtons per kilogram, so the same 3 kilogram object would weigh 4.8 newtons on the Moon.
Work
Force is measured in Newtons and is equal to an object's mass multiplied by acceleration due to gravity. Distance refers to how far an object is moved, either vertically or horizontally. Work is calculated as force multiplied by distance. For example, if an object is pulled 75 Newtons over a distance of 0.025 km, the work done is 1875 Newton meters. Additionally, if 45 Newtons of force lifts an object 65 Newton meters of work, the distance lifted is 1.44 meters.
Work energy power 2 reading assignment -revision 1

Work is calculated as W=FΔx. It also defines kinetic energy as the energy from an object's motion, calculated as KE=1/2mv^2. Potential energy is defined as energy from an object's position. Gravitational potential energy is calculated as GPE=mgh. The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed between kinetic and potential forms. Power is defined as the rate of energy transfer or transformation over time, calculated as P=ΔE/Δt

The forces acting on a bucket suspended by three cables are analyzed. Cable A experiences an upward tension force of 8.01 kN to balance the downward gravitational force on the 817 kg bucket. Using trigonometry and the fact that the system is in equilibrium, the tensions in cables B and C are calculated to be 3.65 kN and 5.66 kN, respectively, based on their angles relative to the x- and y-axes.
Energy
Energy exists in various forms and can be transferred from one object to another or changed from one form to another, but cannot be created or destroyed. There are five main types of energy: kinetic energy (energy of motion), potential energy (stored energy due to position or configuration), chemical energy (energy stored in molecular bonds), thermal energy (the total kinetic energy of random motions of atoms and molecules), and nuclear energy (energy stored in the nucleus of an atom). Kinetic energy depends on an object's mass and speed, while potential energy depends on factors like an object's height, pressure, strain or electric charge. Energy transformations and calculations can be quantified using mathematical equations.

It notes that the greatest tangential velocity in a tornado would likely be at the top due to increased radius, but the highest winds are near the bottom due to increasing barometric pressure and downward spiraling winds.

Newton's Three Laws of Motion
Newton's Laws describe the motion of objects. Newton's First Law states that objects at rest stay at rest and objects in motion stay in motion with the same speed and direction unless acted upon by an unbalanced force. Newton's Second Law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, and inversely proportional to the object's mass. Newton's Third Law states that for every action, there is an equal and opposite reaction. Free-body diagrams are used to identify all the forces acting on an object and indicate the directions of the forces.
Law of Acceleration.pptx
This document defines key terms and concepts related to Newton's Second Law of Motion, including force, mass, weight, and acceleration. It states Newton's Second Law - that the acceleration of an object is directly proportional to the net force acting on it, and inversely proportional to its mass. Several example problems are worked through to demonstrate how to use the law to calculate force, mass, or acceleration given values for the other two quantities.
Forces dynamics
The document discusses different types of forces including magnetic, weight, tension, contact, and friction. It explains that a net force is the sum of all individual forces acting on an object and can cause the object to accelerate. Friction opposes motion and is an example of a contact force that must be overcome for an object to move.

Chapter 6
This document discusses work, energy, and power. It defines work as the product of parallel force and distance. Kinetic energy and gravitational potential energy are forms of mechanical energy. The work-kinetic energy theorem states that work done by net force equals change in kinetic energy. The law of conservation of energy says energy cannot be created or destroyed, only converted from one form to another. Power is defined as work done per unit time. Examples calculate work, kinetic energy, potential energy, efficiency, and power for various situations.
6. forces, density and pressure examples
The document provides examples of calculating density, forces, pressure, and other physical properties. In one example, it is shown that the density of duralumin, an alloy used in aviation, is 3000 kg/m3. Another example calculates the volume and separation of atoms in a cube of titanium weighing 48g. A third example estimates the height of the atmosphere given the density of air at sea level.

The document describes experiments conducted to analyze the motion of a roller coaster on its first drop hill. Two methods were used to measure acceleration, with the first method finding -7.1 m/s^2 and the second -4.9 m/s^2. Height was also measured two ways, with results of 49m and 35.87m respectively. Energy calculations did not match potential and kinetic energies. Forces were measured as 2.81Fg and an average of 2.52Fg from accelerometer data. Overall the data did not fully support hypotheses due to inconsistencies between methods.

This document discusses teen brain development and behavior. It notes that during the teen years, sex hormones enter the scene which can lead to new perceptions and a desire to be with peers. The brain undergoes significant growth during this time, including thickening of the prefrontal cortex and a flurry of growth of neurons, though these prefrontal regions take time to fully develop. This mismatch between brain regions can help explain some impulsive or risk-taking behaviors as the reward system develops before prefrontal regions are fully able to regulate behavior. The document emphasizes that the maturation process for teens involves learning and some trial and error as brains develop.
