No. Accelerate does not mean "to go faster." If car A is going 30mph and car B is going 60mph, car B is going faster but it is not necessarily accelerating.

Accelerate means to increase in velocity over a period time. What Bob said is correct. The measurement of 14 ft per second per second Is a meaure of acceleration. Bob did not say a foul ball accelerates, he just noted the proper use of a term.

[/B][/QUOTE]Straight out of my Webster's New World - "to cause to happen sooner - to go faster, as in my example of pushing the gas pedal (accelerator) to cause the car to go faster. When you are at a stop light and it turns to green and you push the gas pedal you are accelerating. When you get up to the speed limit and put the cruise control on you are cruising at a constant rate of speed, meaured in miles per hour, or it could be measured in feet per second. Feet per second per second (feet per second square) is a measure of acceleration and you are correct, and so was Bob. I just missed the second "per second" when I read his post.
