★Speed:-

i) Distance travelled per unit time is called speed.

ii) It is a scalar quantity.

iii) Only magnitude is required to represent speed.

iv) It is always positive.

v) Speed = Distance / Time.

★ Velocity:-

i) Distance travelled per unit time in a definite direction is called velocity.

ii) It is a vector quantity.

iii) Both magnitude and direction are required to represent velocity.

iv) It can be positive or negative.

v) Velocity = Displacement / Time.
