Question

differentiate speed and velocity ​

Answer 1

Answer:

speed is a scalar quantity

speed cannot be zero

speed is directly proportional to distance

velocity is a vector quantity

velocity can be zero

velocity is directly proportional to displacement

Answer 2

Answer:

Explanation:

 SPEED                      

1. It is defined as the rate of change of distance.

2. It is a scalar quantity.

3. It can never be negative or zero.

4. Speed is velocity without direction.

5. Speed may or may not be equal to velocity.

6. Speed never decreases with time. For a moving body, it is never zero.  

7. Speed in SI is measured in ms-1

 VELOCITY

i. It is defined as the rate of change of displacement.

ii. It is a vector quantity.

iii. It can be negative, zero or positive.

iv. Velocity is directed speed.

v. A body may possess different velocities but the same speed.

vi. Velocity can decrease with time. For a moving body, it can be zero.

vii. Velocity in SI, is measured in ms-1
