Uniform Circular Motion
1.
Describe uniform circular motion.
2.
How is the velocity vector directed when an object travels in a circle?
3.
Is an object that travels in a circular path accelerating? Why?
4.
What is the direction of centripetal acceleration?
5.
What is the direction of the net force acting on an object traveling in a circle?
Inertia and the Right Hand Turn
1.
Which direction do you feel you are sliding in, when you make a right hand
turn as a passenger in a car?
2.
Why do you feel you are being forced leftward or outward when you turning
right?
3.
For how long does the passenger (in blue) continue to follow a straight line?
4.
What do you call an inward force?
The Centripetal Force Requirement
1.
Compare the direction of the unbalanced force to the acceleration. What is the
direction of the acceleration?
2.
Can an object travel in a circular path without circular motion?
3.
Compare the path of the ball (animation) when the block is attached to the
board to when no block is attached to the board.
4.
What supplies the centripetal force required for circular motion?
5.
What happens to a passenger in an auto when the car makes a sudden turn?
