Uniform Circular Motion Quiz
Knowing what you know about uniform circular motion, and physics, when a NASCAR race car speeds around a circular track at 160 mph what keeps it from flying off the sides of the track?
Gravitational Force.
Centripetal Force.
Frictional Force.
Electromagnetic Force.
Strong Nuclear Force.
Imagine you attached a rock to a rope and were swinging it around in a circle very quickly. If you could keep the speed of the rock constant as you pulled the rope in, what would happen to the force transmitted to you by the rope?
Increase inversely with the distance.
Decrease inversely with the distance.
Increase as the square of the distance.
Decrease as the square of the distance.
Remain the Same.
Imagine that this time you were aboard the International Space Station while swinging a rock on a rope around in a circle quickly quickly (so you can neglect the effects of
gravity
) swinging it around in a circle very quickly. Suddenly, the ropa breaks. What did the path of the rock look like before it hit the ISS window a few feet away?
An arc.
A parabola.
A hyperbola.
A line.
It dropped to the ground (and didn't hit the window).
