Newton's Laws of Motion Vocab. Flashcards
Force
A push or a 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 off all of 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 first law
An object at rest will remain at rest and an object in motion will remain in motion unless acted upon an outside force
Newton’s second law
Force=mass x acceleration
Newton’s third law
for every action there is an equal but opposite reaction
Inertia
the tendency of an object to resists being moved or if the object is moving to resits a change in speed or direction until an outside force acts on the object
friction
a force that resists motion
Mass
The mount of matter in an object
Gravity
an attractive force the exists between all objects that have mass
