QUIZ MARCH 10

1. ___________________________ can be used to describe the speed of an object in circular motion

2. ____________________ acceleration is due to a change in direction.

3. Describe the path of an object that is moving whose acceleration is constant in magnitude and is perpendicular to the velocity.

4. If you have tangential acceleration do you have to have centripetal acceleration to have a car move on a race track

5. What is the equation for centripetal acceleration?

1. Tangential speed

2. Centripetal3. Circle4. Yes, must have
