Distinguish between speed and velocity.

Speed

1. Speed is measured as the ratio of distance covered to the time taken to cover.
2. It is a scalar quantity as it has only direction and no magnitude.

Velocity

1. The velocity of an object can be defined as the rate of change of the displacement of the object from its initial position with respect to time.
2. It might sound complicated but velocity is basically speeding in a specific direction.
3. It is a vector quantity.

Difference between speed and velocity

Speed	Velocity
The rate at which an object covers a certain distance is known as speed.	The rate at which an object changes position in a certain direction.
Speed cannot be negative or zero.	It can be negative or zero.
Speed is a scalar quantity.	It is a vector quantity.
Example: A man making a roundabout journey at a speed of 40 kmph.	Example: A woman plans to drive her vehicle at a speed of 76 kmph towards East.
