Give a definition for a force

Force is the push or pull on an object that produce acceleration on the body on which it acts

Force is strength or energy as an attribute of physical action or movement.

Explanation:

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
