This is SIMPLE!

Don't FORCE me!
100
This is used to determine if an object has been moved or not.
What is a fixed reference point?
100
Equal to one newton meter, a metric unit used to measure work.
What is joule?
100
The force that results when two materials rub against each other.
What is friction?
100
A device with few or no moving parts that help to make work easier.
What are simple machines?
100
A push or pull that changes the movement of an object.
What is force?
200
These are three ways to describe motion.
What is speed, velocity and acceleration?
200
For every action there is an equal and opposite reaction.
What is Newton's 3rd Law of Motion?
200
A measure of the steepness of a slope.
What is grade?
200
A beam or bar that pivots on a fixed point.
What is a lever?
200
Separate forces are not equal in strength or they are not opposite in direction.
What is an unbalanced force?
300
The change is an object's velocity over a period of time.
What is acceleration?
300
Force=mass x acceleration
What is Newton's 2nd Law of Motion?
300
An object's resistance to any change in motion.
What is inertia?
300
A straight, slanted surface used to raise an object.
What is an inclined plane?
300
The force that is applied to a simple machine.
What is effort?
400
A measure of an object's speed and direction.
What is velocity?
400
A metric unit used to measure force.
What is a newton?
400
The point where a lever rotates or pivots.
What is a fulcrum?
400
A type of simple machine that is used with a screwdriver.
What are screws?
400
Individual forces that are equal in strength and opposite in direction.
What is a balanced force?
500
A measure of how fast an object can go at a given amount of time or distance divided by time.
What is speed and how it is measured?
500
An object as rest will stay at rest, and an object in motion tends to stay in motion at constant velocity, unless acted upon by an unbalanced force.
What is Newton's first Law of Motion?
500
The force of attraction between any two objects.
What is gravity?
500
The fulcrum is between the effort and load in this class of lever.
What is a first class lever?
500
Mass x Acceleration
What is the mathematical formula for force?
