Speed :
1. Distance travelled per unit time is known as it's speed.
2. Average speed of a moving object cannot be zero.
3. Speed tells how fast an object moves.
4. Speed is a scalar quantity.
5. Speed of an object is always positive.
Example - Light travels with a constant speed in a medium. The speed of light in air = 3×10^8 m/s.
Velocity :
1. The distance travelled by an object in a particular direction per unit time is known as it's velocity.
2. Average velocity of a moving object can be zero.
3. Velocity tells us how fast an object moves and in which direction it moves.
4. Velocity is a vector quantity.
5. Velocity of an object can be positive or negative.
Example-
1- A bus moving towards North on a crowded road.
2- A stone thrown vertically upwards.
Hope this helps!!!!
