Absolutely right my friends. The two cars have the same speed but they are going in the opposite direction so their velocities are different.
An interesting example of the difference between
speed and velocity is when you look at an object moving at a certain speed in a circle. The speed is constant BUT the velocity is constantly changing as the object moves around the circle, see V1 and V2. The velocity at 1 is drawn as a line (representing the speed) pointing in the direction V1. This is a ‘vector’.
Sayed – this site is mainly directed at 8-13 yr olds so the answer above is very ‘general’. I have published it because younger readers might be interested in the difference between the two terms …for more information visit this site.
