Term
 If a particle is in uniform circular motion, what is the angle between the acceleration a, and the velocity v?
Definition
 The angle between v and a is 90 degrees
Term
 A particle is undergoing uniform circular motion, at a speed of v in a circle of radius 4. What is the magnitude of the acceleration, written in terms of v and r, and what is its direction?
Definition
 The acceleration has a magnitude of a = v2/r. The acceleration is directed toward the center of the circular path (centripetal acceleration).
Term
 T or F: The velocity of a body is always parallel to the force being applied to it?
Definition
 False. The acceleration, not the velocity, is always parallel to the applied force.
Term
 T or F: Any kinematic equation involving constant linear acceleration has an analogous equation in angular kinematics.
Definition
 True
