Question

Which of the following is an example of a constant speed but a changingvelocity?A car going around a round-aboutA car merging into another lane on cruise controlA satellite orbiting EarthAll the above

Answer 1

To answer this question we need to remember that the speed is the distance over time, while the velocity is the change of position of the time,

Now, they are gonna be the same if the distance and change of position is the same.

We notice that in the case of a satellite oribitng earth the distance and change of position won't be the same, therefore this is an example of a constant speed but changing velocity
