Answer:
AVERAGE SPEED
THE total distance covered by a body divided by the total time is known as the average speed
AVERAGE SPEED= total distance travelled/total time taken
Uniform speed : If an object covers equal distance in equal interval of time, then time speed graph of an object is a straight line parallel to time axis then body is moving with a uniform speed.
Velocity is defined as the displacement perunit time in a particular direction. its SI unit is m/s.
The short answer is that velocity is the speed with a direction, while speed does not have a direction. Speed is a scalar quantity.
