List 2 things that about velocity and speed that are different and two that are the same.

Hey there!
Speed and velocity both:
1) Measure how fast something is moving
2) Both measured in miles per hour, meters/second, etc (rates)
However, there's a prime difference:
Different because:
1) Velocity is speed, but in a certain direction
2) Velocity is a vector
3) Velocity can be positive or negative, unlike speed.
I added another just in case you had a preference :)

Hope this helps!

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."
