Question

Distinguish between terms (i) speed and velocity (ii) uniform and non uniform velocity.

Answer 1

Now, coming back to uniform and variable velocity, a body is said to be moving with the uniform velocity when it has no acceleration, which means that neither the speed nor the direction of the object are changing with respect to time while the body is said to be moving with the non-uniform velocity if either its speed.
UNIFORM MOTION AND NON-UNIFORM MOTION:A body is said to be in uniform motion, if it travels equal distances in equal intervals of time.A body is said to have non-uniform motion, if it travels unequal distances in equal intervals of time. ... We can say that the motion is called uniform motion.

Answer 2

speed is distance travelled per unit time whereas velocity is the displacement travelled per unit time
speed is scalar quantity
velocity is vector quantity

.................

uniform motion is the equal distance covered in equal intervals of time
whereas
non uniform motion is the motion in which one of the distance or time interval is not equal or both are unequal
