100
Newton's first law of motion is also referred to as this.
What is the Law of Inertia?
100
Change in position of an object, relative to a reference point.
What is motion?
100
Describes the force between magnets, which either attract or repel other objects.
What is magnetism?
100
The speed of a car traveling 60 miles in 20 minutes.
What is s=60miles/20min= 30 miles per minute?
200
The amount of force is measured in these units.

What is Newton's second law?
200
North, south, east, west, up, down, etc. are examples of these.
What are reference points?
200
The tendency of an object to resist any change in motion.
What is inertia?
200
What is Ms. Lambert's velocity if she runs north, 500 feet in 25 seconds ?
What is v=500ft/25sec north= 20 ft per sec north?
300
Forces are this if their net force equals zero.
What is balanced.
300
Newton's law of inertia states this.
What is "An object at rest will remain at rest, and an object in motion will remain in motion unless acted upon by an outside force"?
300
When speed is maintained consistently over time.
What is constant speed?
300
A non-contact force that exerts on every object.
What is Gravity?
300
How long will it take to drive 100 miles if you are traveling at a speed of 50 miles per hour?
What is t=d/s=100 miles/50mph= 2 hours?
400
Motion changes direction or speed, only when two forces are this.
What is unbalanced?
400
This law states, "Every action has an equal and opposite reaction"?
What is Newton's Third Law, The Law of Interaction?
400
A measure of how quickly one object gets from one place to another.
What is speed?
400
A force that stops or slows down motion between two surfaces that are in contact.
What is friction?
400
If you drive 6 hours west at a speed of 60 mph, how far will you travel?
What is d=sxd= 60mphx6hours= 360 miles west?
500
The difference between two forces, in the direction of the larger force.
What is net force?
500
These two factors are inversely related, meaning that as one increases, the other decreases.
What are motion and mass?
500
The formula for velocity.
What is distance/time plus direction?
500
When speed changes over time.
