Net Force
100
Equal forces in opposite directions, produces no motion.
What is a balanced force?
100
What is net force?
The difference and the different forces applied
100
What is newton's law of action-reaction?
For every action there is an equal and opposite reaction
100
An object in motion tends to stay in motion, and object at rest tends to stay at rest.
What is inertia?
100

What is acceleration?
A measurement of how quickly an object is changing speed
200
What is it meant by balanced forces?
There is equal forces acting in the opposite direction.
200

How does friction affect the motion of an object?
It slows down or stops it
300
What is a reaction force?
It is a force acting in the opposite direction.
