The object doing the work loses energy, while the object on which the work is done gains energy. This illustrates the transfer of energy between objects.

These examples show that objects can acquire energy through different means (winding, pressing), enabling them to do work (moving, changing shape, exploding).
If a balloon is pressed too hard, it can explode, releasing the stored energy rapidly and producing a blasting sound.
The balloon changes shape when pressed but returns to its original shape when the force is withdrawn, demonstrating its elastic potential energy.
A fast-moving object has more kinetic energy compared to a slow-moving object of the same mass because kinetic energy is directly proportional to the square of the object’s velocity. This means that even a small increase in velocity results in ...
