Question

(a)  differentiate between speed and velocity.


       (b)  when is a body said to have uniform velocity?


       (c)  how can we describe the position of an object?


       illustrate with suitable example.

Answer 1

a. The short answer is that velocity is thespeed with a direction, while speeddoes not have a direction. Speed is a scalar quantity -- it is the magnitude of the velocity. Speed is measured in units of distance divided by time, e.g. miles per hour, feet per second, meters per second, etc....

b. A body is said to have uniform velocityif it covers equal distance in equal intervals of time in a particular direction, however the time intervals may be small. This means that if abody is traveling at a constant speed along a straight line (i.e, a particular direction) then it said to have uniform velocity.

c. You can describe the motion of anobject by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing. Even things that appear to be at rest move.

Sorry I don't have an example......

But please do me a favour and mark this as brainliest

Answer 2

Answer:

(a) uniform velocity

--------------------------------

when the body covers equal diaplacements in equal intervals of time , it is said to have uniform velocity

-------------------------------------------------

(b) variable velocity

------------------------------

when the body covers unequal diaplacements in equal intervals of time , it is said to have variable velocity
