I googled this but I still don’t get it. I’m not mathematics inclined at all so literally make this a ELI5!

Answer 1

Meters per second is speed. If you move for one second at one meter per second, you travel ome meter. If you move for one second at two meters per second, you travel two meters. A meter is 39.37 inches.

Miles per hour is speed also. If you walk at three miles per hour for one hour, you travel three miles.

Speed is Velocity.

Acceleration is when something travels at a faster velocity for each second. A rock falling from an airplane speeds up as it falls. A penny dropped one foot over your head is nothing. From the top of a skyscraper, it would hit much harder.
