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 ...

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.

This involves two types of energy, potential energy and kinetic energy. Potential energy is the energy an object has because of where it is in relation to other objects. Kinetic energy is what ...
