1) in what way could angular momentum be changed?
Ans) alter the mass, alter the angular velocity, and redistribute the mass
2) You have one screwdriver with a thick handle and one with a thin handle. Which one would be better for opening a stubborn can of paint?
Ans) Either screwdriver--they are the same. I picked this answer because the i believe that the thickness of the handle does not interfere with the screwdriver's ability to pry open a can of paint
3) Which screwdriver would be better for turning a stubborn screw?
Ans) The thick-handled screwdriver
4) How do we know that a force from the Earth acts on the moon?
Ans) I put because the moon orbits the earth
5) What force keeps the moon in orbit around the earth?
Ans) Gravitational force
6) You turn a corner in your car and slide to the outside edge of the seat. Why does this happen?
Ans) Centrifugal force pulls you to the outside
What kind of force does friction provide when your car turns a corner?
Ans) centripetal
8) On a carnival ride, what force keeps you moving in a circle with the ride?
Ans) Centripetal
And can someone explain to me what i should do to solve this problems..with hints, and not answers preferbably.
