How physics relate in the physical world?

Answer 1

Following of our actions in our daily life are parts of physics study.

1)

When we walk or run, our motion is part of laws of mechanics and thermodynamics.

2)

We eat food which undergoes chemical reactions producing heat energy which is converted into mechanical energy.

3)

Use of refrigerator, pressure cookers, washing machines, television, music system, computers, etc. are all designed on the principles of physics.

4)

When we speak, we produce sound properties of which like pitch and intensity are studied in physics.

5)

Electricity that we use in household is a gift of physics.

6)

Automobiles design is based on physics.

The list is endless.

Had there been no study of the science of physics, its development and application in providing all these facilities, we would have remained tribal forever.
