Circular motion is an interesting topic that shows how Newton's First Law of Motion works. This law says that an object at rest will stay at rest, and an object that is moving in a straight line will keep moving that way unless something else makes it change.

Key Points:

1. Same Speed, Different Direction:

   • In circular motion, an object moves at the same speed, but its direction keeps changing.
   • For example, imagine a car driving on a circular track. The car goes at a steady speed, but it always turns to stay on the track.

2. Centripetal Force:

   • The reason the direction changes is because of something called centripetal force. This force pulls the object toward the center of the circle.
   • If there were no centripetal force, the car would just go straight ahead. Picture a ball attached to a string being swung around. If the string breaks, the ball will fly off in a straight line.

3. Real-World Example:

   • This idea helps us understand how satellites move around the Earth. The force of gravity acts like the centripetal force, keeping the satellite going in a circle.

In short, circular motion is a great example of Newton's First Law. It shows that a consistent force is needed to change an object’s direction while it keeps the same speed.
