3
Q
What is α ?
A
Angular acceleration (rad/s^2)
4
Q
What is instantaneous angular velocity?
A
How fast an object is rotating at a specific moment in time.
5
Q
What does angular acceleration change about an object?
A
Its rotational speed

Q
What does centripetal acceleration change about an object?
A
Its direction of motion
7
Q
How do you convert from a rotational quantity to a linear quantity?
A
Multiply by radius
8
Q
What is the equation for the centripetal acceleration of an object moving at a constant speed?
A
a = v^2 / r
