What is the definition of force in science?
Force is a push or pull that affects the motion of an object. Forces are measured in Newtons (N). By studying forces, we can understand why things move the way they do.
Force in Science
Force is a push or pull on an object that results in the object changing speed or direction. It is measured in units of mass × acceleration (Newtons). Inertia is the tendency of an object to resist a change in its state of motion. It is the resistance of any physical object to any change in its state of motion. Gravity is a force that pulls two objects together. It is one of the four fundamental forces of nature.
In scientific terms, a force is a push or pull that can change an object's motion or cause it to change shape. When two objects interact, they exert a force on each other. Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction.

Question: How does a force affect an object in science? Clues: • A force is a push or pull on an object. • Forces can cause an object to speed up, slow down, or change direction. • Forces can be caused by gravity, friction, or a push/pull.
