Question

What are some examples of physical energy?

Answer 1

Hint: The energy to do physical activities is called physical energy. While performing activities, if there is any change in the body physically, then, the energy is said to be physical energy. The examples of the physical energy must include the change in the physical power.

Complete step-by-step solution:
We are asked to find examples of the physical energy, so, we will define the physical energy first.
The energy to do physical activities is called physical energy. While performing activities, if there is any change in the body physically, then, the energy is said to be physical energy. The examples of the physical energy must include the change in the physical power.
The examples of the physical energy are discussed as follows.
Stretching a rubber band – the muscles of the hand and the rubber band gets stretched and then contract on releasing.
Drawing a bow – the muscles of the hand gets stretched.
Riding down the hill – the muscles of the legs get stretched and elongated while paddling.
Jogging/walking/running - the muscles of the legs get stretched and elongated.
Kicking a football - the muscles of the legs get stretched and elongated.
\[\therefore \] The examples of the physical energy are: Stretching a rubber band, drawing a bow, riding down the hill, jogging and kicking a football.

Note: Mainly there are 2 types of energies, they are: potential energy and the kinetic energy. There are further sub divisions of these energies. In the case of potential energy, the types of energies are: chemical energy, mechanical energy, nuclear energy and the gravitational energy. In the case of kinetic energy, the types of energies are: radiant energy, thermal energy, motion energy, sound and electrical energy.
