Our motion perception is remarkably well tuned to detect small changes in speed and direction. For example, soccer goalkeepers need to precisely judge the speed, direction, and curvature of an ...

There are various methods to measure acceleration due to gravity. At Higher level all rely on one of the equations of motion. The measurements required will depend on the equation used. Watch this ...

It doesn't seem like such a difficult question, but it always brings up great discussions. If you drop a heavy object and a low mass object from the same height at the same time, which will hit the ...

We know “what goes up must come down.” But WHY? "Drop" in to find out! We know “what goes up must come down.” But WHY? Drop in to learn about the gravitational forces like acceleration and air ...
