1.3 - Rotational Motion Flashcards
1
Q
what is torque measured in?
A
Nm
2
Q
what does an unbalanced torque result in
A
acceleration
3
Q
what is moment of inertia dependant on
A
the mass of an object and the distribution of that mass around the centre of rotation
4
Q
state the law of conservation of angular 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
define moment of inertia of an object
A
a measure of its resistance to angular acceleration around the centre of rotation
