Question

define

speed
uniform speed
non uniform speed
velocity
average velocity

Answer 1

The definition of speed is...

Speed is a way of measuring how quickly something is moving or being done, or something moving fast. An example of speedis a car being driven 45 miles per hour. An example of speed is someone cleaning a room in 10 minutes.

The definition of velocity is......

Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocityis called "speed", being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s) or as the SI base unit of (m⋅s−1).


The definition of uniform speed is......


Uniform" meaning that the speed and/or the direction has not changed) A body is said to be moving at a constant velocity when the speed of the object has not changed even though the direction may have changed. In other words, constant velocity is a motion with zero acceleration.


The definition of non-uniform speed is.....


If the speed of the body is charging with respect to time, it is moving with a non-uniform speed.


The definition for average velocity is......


the average velocity is this instantaneous averaged over an interval of time.


Thank you for questioning.....

Answer 2

Answer:

UNIFORM SPEED

If a body in motion cover equal distance in equal intervals of time, then the body is said to be in uniform speed

NON -UNIFORM SPEED

If a body covers unequal distance in equal intervals of time, the body is said to be in non-uniform speed

Average speed =total distance travelleeld/time taken to travel the distance
