Question

In which situation are both the speed and velocity of the car changing?

A) the car turns left at 5 m/s

B) the car travels down a straight track at 30 m/s

C) the car travels around a circular track at 30 m/s

D) a car traveling at 30 m/s slows to 15 m/s and turns the corner

Answer 1

Well this is a little hard for a 10 year old but i believe my answer would be c.

Answer 2

Speed is the number that's on a speedometer, and velocity is the same thing, but with a direction.

A and D both have a change in direction, but D is the only one with a change of speed.

Answer is D.
