Question

Difference between speed and velocity

Answer 1

SPEED-

1)the rate of change of distance with time is called speed
2) it is a scaler quantity.
3)speed of a body is always positive

VELOCITY-

1)the rate of change of displacement with time is called velocity.
2)it is a vector quantity
3)velocity of a body can be either positive or negative

Answer 2

Speed:- The rate of change of position of an object is called Speed. It is scaler quality.
Formula:-
S=distance/time

Velocity :- Velocity is the displacement per unit time by an object.It is a vector quantity.
Formula:-
v=displacement/time
