Newton's laws of motion Flashcards
Force
A push or pull is exerted on an object in order to change its motion of the object.
Motion
A change in postion 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 frist 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
Newton’s 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.
