Question

Name the two forms of mechanical energy and also define them. Give 3 examples in this case.​

Answer 1

Answer:

kinetic energy and potential energy

sum of kinetic and potential energy is mechanical energy and it is always constant and SI unit is joule. Potential Energy (PE) KE is the energy possessed by an object by virtue of it being in motion. PE is the energy possessed by an object by virtue of its position. It can be transferred from one object to another and this happens during collision. When the apple is descending, its potential energy has become kinetic energy, which is the energy of motion. Kinetic energy is the energy a person or an object has due to its motion — in this example, the falling apple.
