Here's why:

* Motion refers to an object's position, speed, and direction.

* Forces are pushes or pulls that can alter an object's motion.

Here are some examples of how forces can change motion:

* Pushing a box: A force applied to a box causes it to move from a state of rest.

* Throwing a ball: The force of your throw changes the ball's speed and direction.

* Friction: A force that opposes motion, like friction between a car's tires and the road, can slow down or stop a moving object.

* Gravity: A force that pulls objects towards each other, like gravity pulling a ball downwards, can change its direction and speed.
