Question

9th class physics What the effect of force.​

Answer 1

A force acting on an object causes the object to change its shape or size, to start moving, to stop moving, to accelerate or decelerate. When there’s the interaction between two objects they exert a force on each other, these exerted forces are equal in size but opposite in direction. When an object has several forces acting on it, the effects of force is same as one force acting on the object in a certain direction and this overall force is called the ‘resultant force’. The resultant force is essential to change the velocity of an object.

Answer 2

• Force can change shape or size of a body
• force can stationary move
• force can push or pull on any object .
