Newtons laws 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 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 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 yo resist being moved or, if the object is moving, to resist a change in speed or direction until and 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
