Question #282164
A car moves round a circular track with a uniform speed of 100km/h. Show in a diagram vectors which represents the velocity at four consecutive points A,B,C,D equally spaced round the track.is (A) the velocity and (B) the speed the same at A,B,C,D
Expert's answer
The velocity vectors are represented with the blue arrows.
The velocity is different: although it has the same magnitude (length of the arrow, or vector), it has a different direction. The speed is the same because it only tells us how fast the object moves, it does not have direction.
