Question

Which statement is true?

A.Speed is a scalar quantity and velocity is a vector quantity.
B.Speed and velocity are both scalar quantities.
C.Speed and velocity are both vector quantities.
D.Speed is a vector quantity and velocity is a scalar quantity.
E.Speed and velocity are neither a scalar quantity nor a vector quantity.

Answer 1

Statement ' A ' is true.

Answer 2

A.Speed is a scalar quantity and velocity is a vector quantity.

TRUE

Speed is the ratio of distance and time while velocity is the ratio of displacement and time

B.Speed and velocity are both scalar quantities.

FALSE

velocity is a vector quantity and it is ratio of displacement and time

C.Speed and velocity are both vector quantities.

FALSE

Speed is not a vector quantity but it is a scalar quantity

D.Speed is a vector quantity and velocity is a scalar quantity.

FALSE

Speed is scalar as it depends on distance while velocity is a vector which depends on displacement

E.Speed and velocity are neither a scalar quantity nor a vector quantity.

FALSE

Speed is scalar while velocity is vector
