How can we change the direction of velocity of a body without changing it's speed?
Interesting. Can you give an example of when we would use a centripetal force to change the direction of an object's velocity?
One example would be spinning a ball around in a circle with a string. The ball is constantly changing direction, but its speed stays constant because the force created by the string is perpendicular to the ball's velocity.
