1.
The SI unit of angular momentum is
kg m s−1
kg m2 s−1
kg m2 s−2
N m
2.
A skater pulls in her arms. Which quantity remains constant?
Angular velocity
Kinetic energy
Angular momentum
Moment of inertia
3.
A body has I = 2.0 kg m2 and ω = 5.0 rad s−1. Its angular momentum is
0.4 kg m2 s−1
7.0 kg m2 s−1
10 kg m2 s−1
50 kg m2 s−1
4.
I halves with no external torque. The angular velocity
halves
doubles
quadruples
stays the same
5.
The net torque on a body equals
L/Δt
ΔL/Δt
LΔt
Iω2
6.
A planet moves faster nearer its star because
gravity is weaker there
its angular momentum about the star is conserved
its energy is not conserved
its mass decreases
