Answer 1

1. If we tie a stone to a rope, and start to spin it in a horizontal circle, the tension in the rope is also known as centripetal force.

2. When a body is in uniform circular motion, the speed that is tangent to the circular path is called tangential speed

3. For a body or object to stay in a circular path there must be a force with a direction into the circle

4. In circular motion, the time it takes to complete one round the circle is called a period.

5. The centripetal acceleration keeps the body accelerating towards the center of the circular path
