1) According to work - energy theorem, always total work done by external force equal to change in kinetic energy.( W = ∆E k )
2) The gravitational potential energy of an object depends upon the path the object takes to get to the distance above the reference point (Singh & Rosengrant, 2001, 2003; Herrmann-Abell & DeBoer,2010)[1].
3)Potential energy is an absolut number.
4)The kinetic energy of an object depends on the material an object is made out of. (AAAS Project 2061, n.d.)[1].
5)A lighter object has more kinetic
energy than a heavier object because lighter objects move faster than heavier
objects. (AAAS Project 2061, n.d.)[1].
