Rotation in AP Physics C: Mechanics
What term describes an object's resistance to changes in its rotational motion?
Rotational inertia
Centripetal force
Angular acceleration
Angular momentum
What is the condition for an object to be in rotational equilibrium?
The object must be at rest.
The angular velocity of the object must be constant.
The net torque acting on the object must be zero.
The net force acting on the object must be zero.
What is the angular analog of mass in rotational motion?
Moment of inertia
Angular velocity
Torque
Angular acceleration
What happens to an initially stationary rigid body if only one unbalanced external force acts upon it?
The body will both translate and rotate every time.
The body will remain stationary due to inertia.
The body will translate but not necessarily rotate.
The body will only rotate about its center of mass.
What quantity in rotational dynamics is analogous to force in linear dynamics?
Centripetal force
Angular displacement
Torque
Moment of inertia
Given a non-uniform bar of length that is in rotational equilibrium while supported at two points and with being at one end of the bar; if supports three times more force than , how far from is point located along the bar?
A carpenter uses a wrench to turn a bolt; knowing the bolt requires a tightening torque that is twice the carpenter can apply alone, what effect does doubling the length of the wrench have on the required force?
Doubling the wrench length halves the required force applied by the carpenter.
Doubling the wrench length would require the same amount of force as in the initial scenario.

If a solid disk is rolling without slipping on a horizontal surface, what condition must the static frictional force satisfy at the point of contact?
It must be equal to the product of mass, acceleration, and radius divided by 2.
It must be less than the product of mass, acceleration, and radius.
It must be greater than the product of mass and acceleration.
It can be any value as long as it does not exceed the maximum static frictional force.
If a constant torque is applied to a stationary rigid body, what does the integral of angular acceleration over time yield?
Centripetal force
Angular velocity
Linear acceleration
Moment of inertia
In terms of forces causing rotation, what does imply in static equilibrium for a rigid body?
The object has no potential energy
The net external force on the body is zero
Kinetic friction has ceased acting on the object
No net torque is acting on the body
