7.PS.7 Newton's Laws of Motion Flashcards
A push or a pull exerted on an object in order to change the motion of the object.
Force
A change in position over time.
Motion
The combination of all the forces acting on an object.
Net Force
Distance traveled per rate of time.
Speed = distance/time
Speed
The speed and direction of an object.
Velocity
The rate at which velocity changes over time.
Acceleration
An object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an outside force.
Newton’s First Law
Force = mass x acceleration.
Newton’s Second Law
For every action there is an equal but opposite reaction.
Newton’s Third Law
The tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction until an outside force acts on the object.
Inertia
A force that resists motion
Friction
The amount of matter in an object.
Mass
An attractive force that exists between all objects that have mass.
Gravity
