Newtons Laws of Motion Vocabulary Flashcards
Force
A push or pull exerted on an object in order to change the motion of an 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
Newtons First Law
An object at rest will remain and an object in motion will remain in motion unless acted upon an outside force.
Newtons Second Law
Force = mass x acceleration
Newtons Third 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 on the object.
Friction
A force that resists motion.
Mass
The amount of matter in an object
Gravity
An attractive force that exist between all objects that have mass
