It works on the principle given by a British Physicist William Thompson (later Lord Kelvin) in 1856,which was as follows ÷
When force is applied to any metallic wire its length increases due to the strain. The more is the applied force, more is the strain and more is the increase in length of the wire. If L1is the initial length of the wire and L2 is the final length after application of the force, the strain is given as:
[ ε =(L2-L1)/L1 ]
Hope it will help you.

Answer:
Explanation:
When an object falls freely towards the ground, its potential energy decreases and kinetic energy increases.
As the object touches the ground, all its potential energy gets converted into kinetic energy.
As the object hits the hard ground, all its kinetic energy gets converted into heat energy and sound energy.
It can also deform the ground depending upon the nature of the ground and the amount of kinetic energy possessed by the object.
