As a result, any object in free fall near Earth's surface accelerates at 9.81 m/s/s. The gravitational force acting on an object is not always equal to its weight. A free falling object experiences a ...

James Clerk Maxwell conducted some of the first documented studies of free-falling objects during the mid-1800s, when the physicist analyzed the tumbling motion of a freely falling plate. But much ...

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 ...

Falling objects injured three different people in three separate incidents I recently investigated. The common thread: unsecured objects above the victims’ heads. As in any falling-object case, most ...
