Question

1.Intentify the scaler quantify from the option following option. (option velocity and speed.)​

Answer 1

Answer:

ANSWER

Impulse, force and acceleration are vector quantities since they specify the direction while work done is a scalar quantity. There is no direction in which the work is done.

Work done W=

F

⋅

s

.

Work is a scalar product of force vector

F

and displacement

s

and hence work is a scalar quantity.

Answer 2

Answer:

speed- scalar quantity

velocity- vector quantity
