Question

(xiv) Distinguish between:
(a) displacement and distance, (b) speed and velocity, (c) acceleration and retardation, (d) uniform and
non-uniform velocity, (e) uniform and non-uniform acceleration. ​

Answer 1

Explanation:

Speed Velocity

Speed is a scalar quantity Velocity is a vector quantity.

Speed ascertains how fast a body moves. Velocity ascertains the object's speed and the direction it takes while moving.

Answer 2

Explanation:

Displacement - It is a vector quantity that means direction is necessary to explain it.

Distance - It is a scalar quantity, direction is needed to explain it.

Acceleration - Increase in velocity.

Retardation - Decrease in velocity.

Speed - Distance covered in per unit time and a scalar quantity.

Velocity - Distance covered in per unit time and it's a vector quantity.

Uniform Velocity - If velocity measured at fixed intervals is equal.

Non Uniform Velocity - If velocity is not constant

Uniform Acceleration - If acceleration at fixed intervals are equal.

Non Uniform Acceleration- If acceleration is not equal at fixed intervals.
