Voaculary Flashcards
A location to which another location is compound
Reference point
An objects location
Position
A change of position over time
Motion
A Measure of how fast something moves through a particular distance over a definite time period. Speed is distance divided by time.
Speed
A speed in a specific direction
Velocity
A quantity that has both size and direction
Vector
The rate at which velocity changes over time
Acceleration
A push or a pull; something that changes the motion of an object.
Force
The overall force acting on an object when all of the forces acting on it are combined.
Net force
A scientific law stating that objects at rest remain at rest, and objects in motion remain in motion with the same velocity, unless acted on by an unbalanced force.
Newton’s first law
The resistance of an object to a change in the speed or in the direction of its motion.
Inertia
A scientific law stating that the acceleration of an object increases with increases force spans decreases with increased mass.
Newton’s second law
Any force that keeps an object moving in a circle
Centripetal force
A scientific law stating that every time one object exerts a force in another object, the second object exerts a force that is equal in size and opposite in direction back on the first object.
Newton’s third law
