A graph labeled velocity versus time with horizontal axis time (seconds) and vertical axis velocity (meters per second). A blue line runs straight across at 2 units on the vertical axis for all horizontal axis values.

How is speed calculated?

Newton’s first law of motion was a giant leap forward in scientific thought during Newton’s time. Even today, the idea is sometimes difficult at first for people to understand.
