What is the equation for linear kinetic energy?

K=1/2mv2

200

What is torque

T, it is a twisting force that causes rotation, can be solved by multiplying the force by the distance from the radius.

What is the equation for linear momentum?

p=m*v

What happens when energy is lost from a system?

Work is done!

400

Can there be rotational kinetic energy?

Yes! It's formula is K=1/2Iw2

400

Can momentum be conserved? How so?

Yes! Momentum is conserved when no momentum is lost from the system!

Ms. Maas is spinning on her chair. She sticks her arms and legs out and slows down. Why does this happen?

Because she increased her rotational inertia, so her angular velocity decreased. This is because momentum is conserved while she's spinning in her chair and we use the equation L=I*w
