Cbse class 8 science notes chapter 11 force and pressure a push or pull exerted by an object on another is a force. So the total force applied on the heavy object is f1 f2 towards right if forces are applied in the opposite direction then the net force acting on the object is the difference between the forces and the object tends to move in the direction of the greater force. In case ii if f1 f2 the net force on the object is f f1 f2 0.

Chapter 11 class 8 force and pressure. Contact forces and non contact forces. Iv whenever force act two object are involved. Forces which take place when objects touch each other.

Force has both magnitude and direction. Force and pressure class 8. Force that arises with the contact of 2 or more objects involved. A description of an interaction that causes a change in an object s motion.

Ii living and non living things can apply force. Muscular force and frictional force. Contact forces can be classified according to six types. When the interaction ceases the two objects no longer experience the force.
