RBSE Class 8 Science Chapter 11 Notes Force and Pressure

→ When we push or pull a body, in science we say that a force is applied. Force is the result of interaction between the two bodies.

→ The strength of a force is usually measured by its magnitude, but force also has a direction.

→ Force can cause a change in the state of motion and also the direction of motion of the body. Force can also change the shape of the body.

→ A force can act on an object with or without being in contact with it.

→ Force per unit area is called pressure. Liquids and gases exert pressure on the walls of their container. The pressure exerted by air around us is known as atmospheric pressure.
