Newton's Laws of Motion Flashcards
Force
A push or pull is exerted on an object to change its motion of that object.
Motion
A change in position over time.
Net Force
The combination of all the forces acting on an object.
Speed
Distance traveled per weight per 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 by 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 resist being moved, or if the thing is moving, to fight 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.
