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. |
