Uniform Circular Motion Quiz

The velocity vector is _____ to the acceleration vector

The Acceleration vector is always pointed towards the ______ of the circle

The relationship between Period and Frequency is a(n) _____ relationship

True or False: When a ball attached to a string is moving in a circular vertical motion, the two forces applied on it is Force of Tension and Force of Friction

True or False: Centrifugal Force is the Force that pushes an object toward the circle

True or False: The Centripital force is in the direction of the acceleration

A popular daredevil trick is to complete a vertical loop on a motorcycle. This trick is dangerous, however, because if the motorcycle does not travel with enough speed, the rider falls off the track before reaching the top of the loop. What is the minimum speed necessary for a rider to successfully go around a vertical loop of 10 meters?

Two spherical objects have masses of 200 kg and 500 kg. Their centers are separated by a distance of 25 m. Find the gravitational attraction (force) between them. No Units needed

What is the period of an object that makes 5 rotations in fifty seconds? No Units needed

What is the frequency of an object that makes 5 rotations in fifty seconds? No Units needed

A 0.65 kg ball is attached to the end of a string. It is swung in a vertical circle of radius 0.50 m. At the top of the circle its velocity is 2.8 m/s. Find the Tension in the string.

A 45 kg physics student is riding on a roller coaster that enters a vertical loop of radius 30 m. At the bottom of the loop the velocity of the roller coaster cart is 12 m/s. Find the normal force on the student.

With an object in UCM, what would happen to the net force if the radius remains the same and the speed was doubled. It____________

What is the apparent weight of an astronaut in space, when orbiting the earth
