### Kinetic Theory

Kinetic theory (or the kinetic or kinetic-molecular theory of gases) is the theory that HYPERLINK http//en.wikipedia.org/wiki/Gasgases are made up of a large number of small particles (HYPERLINK http//en.wikipedia.org/wiki/Atomatoms or HYPERLINK http//en.wikipedia.org/wiki/Moleculemolecules), all of which are in constant, HYPERLINK http//en.wikipedia.org/wiki/Randomnessrandom HYPERLINK http//en.wikipedia.org/wiki/Motion_(physics)motion. The rapidly moving particles constantly collide with each other...

### Kinetic Energy

Kinetic Energy: Consider a baseball flying through the air. The ball is said to have "kinetic energy" by virtue of the fact that its in motion relative to the ground. You can see that it is has energy because it can do "work" on an object on the ground if it collides with it (either by pushing on it and/or damaging it during the collision).  The formula for Kinetic energy, and for some of the other forms of energy described in this section will, is given in a later section of this primer. Potential...

### Materials Used for Vehicle Armour

armour is bulkier than steel plate armour but is lighter and more effective against high explosive anti-tank (HEAT) rounds and kinetic energy penetrators. HEAT rounds use high density explosively formed projectiles to push through armour. Kinetic energy penetrators are made from the densest material available and are long rods fired at high speeds. The weapon uses the kinetic energy from the speed and density of the projectile to push through the armour in one small area. As the HEAT round penetrates...

### Potential Energy

﻿examples of work done=force x distance What is work? Work in physics is the transfer of energy; work is done on an object when an applied force moves it through a distance. The link between work and energy is work done equals energy transferred. The units for the two are also the same (joules). E.g. 500J of work = 500J of kinetic energy. Work is calculated with the formula: work done=force x distance moved For example, if a force of 10 newton (F = 10 N) acts along point that travels 2 meters...

### Energy and Block

What is their difference in momentum? What is their difference in kinetic energy? 2. A 12 g bullet is fired horizontally into a 96 g wooden block initially at rest on a horizontal surface. After impact, the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.60, what was the speed of the bullet immediately before impact? You have to use the conservation of the total energy of the system to do this problem:  Initially, you have, in the...

### Energy Lab

Energy Lab On November 13th, we did a lab to learn about energy. The definition of Kinetic Energy is energy of movement. The definition of Gravitational Potential Energy is energy in an object due to its positioning. The question that we had to answer was whether of not we could calculate the Gravitational Potential Energy and Kinetic Energy of various objects in different locations. To do this lab we had to first weigh the given objects. For this time, we weighed : a marble, a bouncy ball,...

### Energy and Efficiency

Calculating Efficiency. Efficiency (%) = Useful Energy Out x 100 Total Energy In Questions 1) A light bulb takes in 30J of energy per second. It transfers 3J as useful light energy and 27J as heat energy. Calculate the efficiency. 2) A kettle takes in 2000J of energy per second. It transfers 1500J as useful heat energy and 500J is wasted as sound energy. Calculate the efficiency of the kettle. Remember: In the exam they may not...
