Two cars are moving with speed 40 km/h due north and 40km /h due south respectively do they have sme velocity
Answers
Answer:
Explanation:
velocity is a vector quantity and it depends on direction also
here magnitudes are same but direction is not same
hence two cars don't have same velocity but they do have same speed
Answer:
They do not have the same Velocity
Explanation:
Firstly, What is a Vector Quantity & Scalar Quantity?
A scalar Quantity is a physical quantity that is expressed only by the magnitude of the body. Whereas, a Vector Quantity is a physical quantity that is expressed by both the direction and the Magnitude of the body...
Coming back to the question...
Velocity is a Vector quantity. So, we have to keenly observe both the magnitude and DIRECTION. Even though the 2 cars are moving at the same speed, their Direction is different... If the question was, "do they have the same Speed?" then the answer would have been "Yes." Because Speed is a Scalar quantity - and as both cars have the same magnitude, the answer will be true...
but in this case, they are asking whether the Velocity is the same... The answer will be "No" because the direction is different...
Hope this helped u...
