Question

difference between speed and velocity​

Answer 1

The short answer is that velocity is the speed with a direction, while speed does not have a direction. velocity is a vector quantity. 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.).

Answer 2

Speed

1. It is the distance travelled by a body in unit time
2. It is a scalar quantity
3. it can be changed by the distance travelled by a body in a particular time
4. It is always positive or zero but can never be negative.

Velocity

1. Velocity is the speed of an object moving in definite direction.
2. It is a vector quantity.
3. It can be changed by changing the speed of a body.
4. It sometimes may be positive, zero or negative.
