The film explains the conversion of mechanical energy and thermal energy using examples like a bouncing ball and gas molecules. It discusses the principles of kinetic and potential energy, the ...

The balls gain potential energy as they are mechanically lifted, before this is converted to kinetic energy when they begin rolling, plus sound energy from hitting drums and gongs. The museum's ...

we can say that: 2000 J of work has been done in getting the object to that height from the ground If an object, such as a ball is lifted above the ground it has gravitational potential energy.

The amount of energy in the kinetic energy store depends on the speed of the object. The box has more energy in its gravitational potential energy ... dropped a number of balls from different ...
