Question

how is force useful ?​

Answer 1

Answer:

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.

Answer 2

Answer:

Everything on Earth is powered by forces, pushes and pulls which act on our bodies and the things around us. Forces make things move and stop moving.
