Force

A force is a push or pull that acts on an object. If the force is greater than the opposing force, the object will change motion or shape. Examples of forces are gravity and the wind. The size of a force is often measured in Newtons or pounds. Spring balances are used to measure forces/Newtons because springs are elastic and stretch. The amount of an elastic body stretches is in direct proportion to the force acting on it. This is known as Hooke’s Law
