Use Fleming’s left-hand rule to remember the direction of motion in an electric motor. It is shown in the following diagram. A current-carrying wire or coil can exert a force on a permanent magnet.

A streamline is a line that is tangential to the instantaneous velocity direction (velocity is a vector, and it has a magnitude and a direction). To visualize this in a flow, we could imagine the ...

The peripheral drift illusion causes us to perceive motion in a still image. A new study shows that the mechanism of this illusion relies on changes in pupil size.

If you choose to select the Custom Path Motion Path, you can draw the path you want the object to take. To stop drawing the Custom Path, press the ESC key on the keyboard. To change the direction ...

To treat motion sickness try facing forward in the direction of travel and getting fresh air. If you feel sick while riding in a car, train, or plane, you're not alone — around one in three ...
