Question

Differentiate between speed and velocity of a body. Out of the two which have the zero mean
value for a moving body? Give one example.
​

Answer 1

Answer:

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is direction-aware.

Velocity can have a zero mean value but speed cannot have as displacement can be zero,negative or it can be positive

Explanation:

Answer 2

Explanation:

Velocity :

1. Its si unit is m/s
2. it is vector quantity
3. It can be zero

speed ;

1. Its si unit is km/hrs
2. It is scalar quantity
3. it never be zero

Speed
