1)
Rotational analogue of force is called
Tension
Angular momentum
Torque
Angular acceleration
2)
When torque of a rotating body is zero, which among the quantity is conserved?
Moment of inertia
Angular acceleration
Force
Angular momentum
3)
Let M,R be the mass and radius of flywheel, what happens to its moment of inertia I when the mass is doubled and radius is reduced to half
No change
Reduced to one fourth
Doubled
Reduced to half
4)
A flywheel starts from rest and gains an angular velocity ω=5t²rads⁻¹.Find its angular acceleration α
10t rads-²
5rads-²
5t rads-²
5/3t³rads-²
5)
