Term

Definition
A branch of mechanics which describes the motion of an object without ecplicit reference to the forces that act upon an object. 


Term

Term

Definition
Velocity  the rate of motion in a given direction of the rate of displacement
Speed the rate of motion / rate of distance 


Term

Definition
the rate of a displacement at a particular moment of time and a particular point of a path of motion. 


Term
Average velocity and average speed 

Definition
Average velocity is a vector physical quantity that is equal the ration of a displacement over a timeinterval.
Average speed is a scalar physical quantuty that is equal to the ration of a distance over a time interval.
