Newton´s Laws Flashcards
Force
A push or a pull exerted on an object in order to change the motion of the object.
Motion
A change of 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.
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 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.
