Give three examples of each:
elastic collisions perfectly inelastic collisions
If a skater with a mass of 50 kg runs up
at 5 m/s to a 5 kg skateboard resting on the ground, what will be the resulting
speed of the skater on the board when he jumps on it?
Chapter 7/8: Rotational Motion
What is Newton's law of universal gravitation?
Why do we talk about “rotational speed”
instead of “rotational velocity”?
Why does mud fly off a rotating wheel?
(Your answer must contain the word “force” and must explicitly reference
to several other variables.)
Why is the moment of inertia of a tether
ball swinging on a rope greater
than spinning a stick of equal mass around? (In other words, why are the
formulas different for the two objects?)
What is the relationship between force
and distance for simple machines?
Let’s say you are using a crowbar to pry
open a sealed wooden chest. It takes 550 N of force at the tip of
the crowbar to break it open when the tip is 0.05 m from the fulcrum.
If you had your hands 0.95 m from the fulcrum, how much force did you need
to use to get to the treasure?
What are the two families of simple machines
and what simple machines do they include?
Chapter 12: Waves

Janet wants to find the spring constant
of a given spring, so she hangs it vertically and attaches a 0.5 N mass
to the end. What is the spring constant if the spring stretches 3.0
