Hewitt-Drew-it! PHYSICS 43. Angular Momentum

What is the equation for linear momentum?

• p=W/t

• p=ma

• p=mv

• p=mgh

If the length of the string were increased (and the speed stayed the same), what would happen to the angular momentum?

• stay the same

• increase

• decrease

Angular momentum is conserved unless what acts on it?

• potential energy

• net torque

• kinetic energy

• net force

When he pulls his arms in what will happen to his rotational speed?

• stay the same

• increase

• decrease

How are rotational speed and rotational inertia related when angular momentum is conserved?

• directly

• inversely

• not related at all

What would happen to the rate of rotation?

• Stay the same

• Stop completely 

• Slow Down

• Speed up
