Balanced Force
Two forces in opposite directions. Net force is zero and the motion of the object does not change.
Friction
The force between objects that resists motion - always slows down motion
Newton
A measurement of force
Mass
The total amount of matter in something.
Force
A push or pull on an object that can cause a change in movement
Net Force
The total of all the forces acting on an object
Gravity
A force that pulls objects together
F = m x a
Formula for Force
Newton's First Law of Motion (Definition)
an object at rest will stay at rest unless acted upon by an outside unbalanced force; an object in motion will stay in motion unless acted upon by an outside unbalanced force.
Newton's Second Law of Motion (Definition)
the greater the force applied to an object, the greater the acceleration; the smaller the mass of an object, the greater its acceleration when force is applied; only an unbalanced force can cause objects to accelerate
Newton's Third Law of Motion (Definition)
for every action there is an equal and opposite reaction; there is a reaction force that is equal in size but opposite in direction.
Unbalanced Force
A force that is not equal in size and opposite in direction.
newton's second law
F=ma
Newton's 3rd law
Every action has an equal and opposite reaction
This force goes in the opposite direction of motion
Friction
