This is a change in a position over time.
What is Motion
200
The rate at which velocity changes.
What is acceleration?

The pressure caused by the weight of the atmosphere
What is What is atmospheric pressure
400
How are distance, time, and speed related.
You need to find out distance and time to find speed
