Force
Net Force
Motion
Friction
100
The unit used to measure force is this
What is NEWTON?
100
This is the symbol used to measure force
What is capital N?
100
Force is the cause of this
What is MOTION?
100
A force that opposes the movement between two touching surfaces.
What is FRICTION?
200
Describe the relationship between force and acceleration
What is as force increases, acceleration increases
200
Describes the total (sum) amount of all forces acting on an object.
What is NET FORCE?
200
This is the number of Laws of Motion there is
What is THREE?
200
When friction is occurring, these two things happen to an object
What is slow down and stop moving?
300
This is needed to change the motion of an object (an unequal amount of force)
What is an UNBALANCED FORCE?
300
When calculating net force, this should be done if all the forces are in the same direction
What is ADD THEM?
300
This Law of Motion states that for every action, there is an equal and opposite reaction
What is the Third Law of Motion
300
Friction produces this type of energy
What is THERMAL/HEAT?
400
This type of force can be at rest or in motion, but must have an equal amount of force
What is BALANCED FORCE?
400
When calculating net force, this should be done if all the forces are in opposite directions
What is SUBTRACT THEM?
400
This is a way that we measure how fast or the speed of something
What is acceleration?
400
This would happen if there was no friction
What is everything would slide?
500
Force can change these three things in an object
What is speed up, slow down, and change direction?
500
This is the net force of the people in the diagram
What is 50 N Left?
500
This person got the idea for gravity when an apple fell off a tree and hit him on the head
Who is Isaac Newton?
500
Using water, wheels, or making surfaces smoother
What is how to reduce friction?
