A student states that the velocity of a train is 95 kilometers/hour. What is wrong with that statement?


The units should be in kilometers/second/second
Velocity must include a speed and direction
Velocity is a measure of the change in speed over time.
Velocity is the distance an object travels in seconds, not hours.

I'm not sure on this question. I think it either B or C. Please correct me if I'm wrong.

the speed is 95
the velocity also has to specify direction

Remember, for velocity you need speedometer AND compass.

ACCELERATION is rate of Change of Velocity

b
Thank you! I wasn't quite sure on this question. Also that was my last question. Thanks aging for checking my questions!
By the way km/h is a perfectly good way to specify speed. However once you get into calculating accelerations and stuff you will need to convert that to meters/second
You are welcome, good luck. Remember that speedometer and compass.
