Forces and motion are all around us! A force is a push or a pull that can make something move, stop, or change direction. Motion is when something is moving from one place to another. Everything that moves is affected by forces like gravity and friction.
Imagine kicking a ball. Your foot applies a force, sending the ball into motion. The ball might slow down because of friction from the grass and eventually stop. Understanding forces and motion helps us understand how the world works! 🌍
