... • Kinetic energy depends on two things: mass and speed. • Kinetic energy increases with speed. Consider a shopping cart with a certain speed. To make the cart move faster you need to apply a force to it. Applying a force means you have to do work. The higher the speed of the cart, the more energy it ...

... Power is measured in joules per second (J/s) and one joule per second is known as a WATT (symbol W). WORKED EXAMPLE A man of mass 80 kg runs up 20 steps in 8 seconds. If each step is 25 cm high, what is his power? Weight of man = 80 kg x 10 = 800 N Total height in metres = 20 x 25 = 500 cm = 5.0 met ...

... Consider the specific heat of copper, 0.385 J/g 0C. What this means is that it takes 0.385 Joules of heat to raise 1 gram of copper 1 degree Celsius. Thus, if we take 1 gram of copper at 25 0C and add 1 Joule of heat to it, we will find that the temperature of the copper will have risen to 26 0C. We ...
