Question

what is force ? what happens when force is applied on the object in the same direction or in the opposite direction?

Answer 1

Force is a pull or push which changes the motion or shape of the body or has the tendency to change motion or shape of the body.

Force can be measured as the product of mass and the acceleration produced in the body by the force.

F = mass* acceleration.

The force changes the state of rest or motion of body and also it can change shape or size of the body.

When force is aaplied in the direction of motion it increases the velocity and when applied in opposite direction it decreases the velocity and even it can stop the motion of body also.
