Rotational Motion Flashcards
1
Q
What happens when a torque is unbalanced
A
causes an acceleration
2
Q
what is moment of inertia dependant on
A
the mass and radial distribution of the mass around the centre of rotation
3
Q
what is moment of inertia
A
how much an object will resist angular acceleration
4
Q
what is the law of the conservation of momentum
A
in collisions the total angular momentum before a collision is equal to the total angular momentum after a collision in the absence of external torques
5
Q
what is meant by central force
A
the force which causes an object to remain in circular motion
