Force Flashcards
A push or a pull exerted on an object in order to change the motion of the object
Net force
The combination of all forces acting on amn object
Motion
A change in position over time
Speed
Distance traveled per rate of time. speed = distance/time
Velocity
The speed and direction of an object.
Acceleration
the rate of which velocity changes over time.
Newtons first 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.
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 exists between all objects that have mass.
