Newtons law of motions Flashcards
Force
A push or 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.
Newtons first law
An object at rest will stay at rest will remain at rest an object in motion will stay in motion unless acted upon by an outside force.
Newtons second law
Force= mass x acceleration.
Newtons third law
For every action there is an equal but opposite reaction.
Inertia
The tendency of an object to resist being moved or, f the object is moving, to resist a change in speed or direction until an out side force acts on the object.
Friction
A force that resists motion.
Mass
The amount of matter in an object.
Gravity
An attraction force that exist between all objects that have mass.
