### Dropping a ball and calculating its speed.

· Not "speed" of gravity, acceleration due to gravity. If the acceleration is m/s^2 then the speed after t seconds is v= + v0 (v0 is the initial speed and I am taking positive downward) and then the distance traveled is s= ^2+ v0t. Since the ball is "dropped" the initial speed is 0 so we have v= and s= ^2.

### Speeds and Feeds Calculator

### Time, Velocity, and Speed

Average speed, however, is very different from average velocity. Average speed is the distance traveled divided by elapsed time. We have noted that distance traveled can be greater than displacement. So average speed can be greater than average velocity, which is displacement divided by time. For example, if you drive to a store and return home in half an hour, and your …
