Expert Answer:
Parameters
Speed
Velocity
Definition
Distance traveled by a body in unit time
Distance traveled by a body in a particular direction in unit time
Scalar/Vector
Scalar
Vector
Physical interpretation
Speed tells how fast a body moves
Velocity tells the direction of the body and how fast a body is moving
Sign
Always positive
Can be negative, positive or even zero
Acceleration - The rate of change of velocity is called acceleration.
