A push or a pull is called what?
What is Force?
100
This law states that for every action, there is an equal and opposite reaction.
What is Newton's Third Law of Motion?
100
The force that keeps the planets in their orbit around the sun.
What is gravity?
100
You calculate the ___________ when you divide the distance traveled by the time it takes to travel that distance.
What is speed?
200
This is the change in speed or direction over a period of time.
What is Acceleration?
200
Newton's first law of motion states that an object that is moving will continue to move until an outside force acts on it to make it stop. The next part of this law is
What is an object at rest will remain at rest until an outside force acts on it to make it move?
200
The force that always opposes motion, works against motion to slow things down.
What is Friction?
200
A sling shot is an example of what type of potential energy?
What is Elastic Potential Energy?
300
Forces that are the same size but opposite in direction.
What are Balanced Forces?
300
The science term used in reference to Newton's first law of motion.
What is Inertia?
300
For something to move, the forces must be what?
What is an Unbalanced Force?
300
If the forces are equal but opposite, balanced forces, then there will be no ________________.
What is motion?
400
The resistance of an object to changes in its motion.
What is Inertia?
400
F=m x a
What is the formula for Newton's 2nd Law of Motion?
400
The pair of forces discribed in Newton's 3rd Law?
What are action-reaction forces?
400
Either speeding up, slowing down or changing direction will cause ______________________
What is Acceleration?
500
Two types of potential energy

What is Newton's Third Law of Motion?
500

A marble would roll around in a pie plate in a circular path until it reaches the part where a section is cut out. At that section the marble would: A) roll in a straight path at a constant speed from the edge of the pie plate or B) continue to roll in a circle around the pie plate. Pick what the marble will do and tell why.
What is roll in a straight path at a constant speed from the edge of the pie plate because of Newton's First Law of Motion?
