Question

What is meant by mechanical energy? Explain its forms with examples.

Answer 1

Mechanical energy:

1. The energy possessed by a body due to its position or state of motion is called it's mechanical energy.
2. It is of two types:

1. Kinetic energy:

1. It is the energy possessed by a body due to its state of motion.
2. For example, A moving car has kinetic energy due to its motion.
3. A falling stone has kinetic energy.

2. Potential energy:

1. It is the energy possessed by a body due to its position.
2. It is of two types, elastic potential energy and gravitational potential energy.
3. For example, A stretched rubber band has elastic potential energy due to its changed shape.
4. Fruit on a tree has gravitational potential energy due to its height above the ground.
