Newton's Laws of Motion Vocab Flashcards
Force
A push or pull exerted on an object in order to change the motion of the object.
Motion
A change in position over time.
Net force
The combination of all the forces acting on an object.
Speed
Distance traveled per rate of time - Speed = distance/time
Velocity
The speed and direction of an object.
Acceleration
The rate at which velocity changes over time.
Newton’s 1st law
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 2nd law
Force = mass * acceleration
Newton’s 3rd law
For every action there is an equal but opposite reaction.
Inertia
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 in the object.
Friction
A force that resists motion.
Mass
The amount of matter in an object.
