Newton's first law says this.
What is an object in motion will stay in motion and an object at rest will stay at rest until acted on by an unbalanced force?
100
A force can be defines as this.
What is a push or a pull?
100
Tom pushes a table with a force of 6 N to the left. Tina pushes the table with a force of 12 N to the right. The table has a motion in this direction with this amount of net force.
What is 6N accelerating to the right?
100

This term is the opposite of rest.

Motion

What is the force on a 500 kg small elevator falling freely on Earth?

4900 N

200
Newton's 1st law of motion can also be referred to as the law of ____________.
What is intertia?
200
This type of force causes an object to move in a circular path.
What is a centripetal force?
200
Michael is arm wrestling Michelle. Michael exerts a force of 10 N to the left and Michelle exerts a force of 10 N to the right. The net force is this.
What is 0N (no motion!)?
200
This term can be used to describe the tendency for an object to resist a change in motion and stay at rest.
What is inertia?
200
An object with a mass of 8 kg is acted upon by a 16 N force to the right. What will its acceleration be?
What is 2 m/s?
300
Newton's 2nd law of motion relates force, mass, and acceleration using this formula?
What is force = mass x acceleration?
300
If two forces act equally, but in opposite directions they are said to be ____________ forces
What is balanced?
300
A basketball is rolling across the floor to the right direction. Susan pushes it with a force of 15N to the right. Sally pushes it with a force of 12N to the left. This is the overall motion and net force of the object.
What is accelerating to the right with a net force of 3N?
300
This term can be classified as balanced or unbalanced based upon the net calculation.
What is force?
300
What is the net force of the following (20 N pulled up, 49 N pushed down)?
What is 29 N downward push?
400
For Newton's 2nd law of motion, it is suggested that an object with a greater mass will require a greater______ to act upon it.
What is force?
400
This unit is used to measure force
What is a Newton?
400
If an object is moving to the left at a speed 5 m/s and a wind with a force of 2N is acting in front of it and behind it, this will happen to its velocity.
What is nothing? It will maintain it's motion because the net force is 0!
400
If an object speeds up from one velocity to another, it is said to have demonstrated this.
What is acceleration?
400

A force of 500 N accelerates an object 20 m/s/s.  What is the mass of the object? 

25 kg

500
Newton's 3rd law of motion relates the relationship between two forces and can be summed up by these two words.
What is action-reaction?
500
If one force is greater than the other, the net force is said to be this.
What is unbalanced?
500
Assume an object at rest is pushed to the right with a force of 4N and pulled up with a force of 12N. What is it's overall path of motion?
What is slightly to the diagonal right?
500
The root centri- as seen in centripetal force means this.
What is circle?
500

A 1500 kg car rounds a 30 m corner at 12 m/s.  Ignoring friction, how much centripetal force is exerted in this situation? 

7200 N
