Motion And Forces Flashcards
A location to which another location is compared
Reference Point
A object’s location
Position
A change of position over time
Motion
A measure of how fast something moved though 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
A push or pull; something that changes a motion of a object.
Force
The overall force of acting on an object when all of the forces acting on it are combined.
Net Force
A scientific law that objects remain at rest, and objects that are in motion remain in motion with the same velocity, unless acted by a unbalanced force.
Newton’s First Law
The resistance of a object to change in the speed or the direction of its motion.
Inertia
A scientific law stating that the acceleration of an object increases with increased force and 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 on 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
