This video is just asking to be a physics problem on my final exam. Here we have someone launched into the air with a slingshot. The fellow then opens a parachute and floats back to Earth. I'm not ...

Displacement close displacementA distance measured in a specified direction. is the distance moved in a straight line, in a given direction, from the starting point. Displacement = 24 m east. Velocity ...

Here is classic (and difficult) physics problem that poses an interesting question: Take two points in space, Point 1 and Point 2. What is the path from point 1 to 2 that a frictionless object could ...

Note that since the top contact point of the disk rolls without slipping on the upper fixed surface, this contact point has zero velocity. In addition, the horizontal component of acceleration of that ...

Long cardboard tube, such as an empty roll of wrapping paper, to make your ramp. It should be at least two-and-one-half feet long. A thin book or small wood block to raise one end of your ramp. It ...

Introduction Have you ever played a video game with a controller that used motion controls? Do you ever wonder how sometimes a smartphone seems to "know" if you're moving? How do these electronic ...
