What is "If object A exerts a force on object B, an equal but opposite force is exerted by object B on object A." (Also accepted is, "For every action there is an equal and opposite reaction.")

How much gravitational pull does a bear have?
As much as it weighs.
100
The condition of unrestrained motion.
What is freefall.

Why did the eggs fall and break when Ms. Stockley dropped them off the school roof?
What is gravity.
200
What kind of gravity is in space?
Microgravity

When Moby pushed the door while wearing rollerblades, why did he accelerate backwards?
Because the door pushed him with the same amount of force.

What was the most interesting experiment?
Really, that was your favorite?
200
The force caused by two objects rubbing together.
What is friction.

Imagine your car has skis on top of it and you hit the brakes. If your car suddenly stops and your skis aren't tied down, what will happen to your skis?
First, why are you driving?
Anyway, your skis will keep going.

What accelerates faster (given the same amount of force), a wooden ball (10g) or a steel ball (100g)?
Wooden ball

Does the reaction force have more or less force than the action force?
Neither, it has the same amount of force (trick question)!

Name something that has a strong gravitational pull.
If you wrote Mr. Noyes, you are in trouble!
300
The strength of an object's motion.
What is momentum.

An object remains in motion, like a ball rolling across the ground. What causes it to stop?
Gravity & friction

If you place a spring jumper on the table, what causes the action force?
The spring

What will have the greatest acceleration, an object with more mass or less mass?
Less mass

If a spring jumper is compressed and jumps on a table, what causes the reaction force?
The table

Name one thing you can do to slow down your egg drop experiment (the acceleration from the roof).
Answers will vary, but you need to have some air resistance
