Physics final

Which is designed at ½ pi of a revolution?

The Radian

Which is the change in the angles as an object rotates

Angular Displacement

which is the number of complete revolutions made by an object in 1 s

Angular frequency

Change in Angular velocity depends on:

magnitude of the force, distance, direction of the force

Torque

how effectively a force causes rotation

Resistance to rotation

moment of inertia

if the torque of an object and the angular velocity of an object are in the same direction…then the angular velocity what

increases

if torque and angular velocity are in different directions then angular velocity what

decreases

what defines a lever arm

the perpendicular distance from the axis of rotation to the point where the force is exerted

Newtons second law for rotational motion

directly proportional to the net torque and inversely proportional to the moment of inertia
