# Newtons Laws

1st law Motion-the action or process of moving or being moved Inertia- the property of matter by which it retains its state of restor its velocity along a straight line so long as it is not actedupon by an external force. the property of matter by which it retains its state of restor its velocity along a straight line so long as it is not actedupon by an external force. , Push-exert force on (someone or something), typically with one's hand, in order to move them away from oneself or the origi…

Motion
Action or process of changing position
Inertia
The tendency of an object to resist a change in motion
Balanced force
Equal forces acting on an object in opposite directions
Mass
Amount of matter in an object
Forces
A push or a pull that causes objects to move or change position
Unbalanced force
When the forces on an object are pushing harder in one direction than in another, causing movement
Velocity
Speed of something in a given direction
Net force
The sum of all forces acting on an object
Acceleration
Rate of change of velocity
Gravity
Force of attraction between objects that is due to their masses.
Weight
Amount of gravity pulling down on an object
Newton's first law
An object at rest will stay at rest, an object that is moving will stay moving unless disturbed by an unbalanced force.
Newton's second law
Force is mass times acceleration
Newton's third law
For every action there is an equal and opposite reaction
Friction
A force that opposes motion between two surfaces that are in contact
