When an object is falling, the two main forces acting on it are weight close weightA force that acts on mass, pulling it down, due to gravity. Weight is a force and forces are measured in newtons (N).

If a velocity-time graph of the motion shows a rising or falling line, this means that the velocity is changing. Therefore the forces acting must be unbalanced, and the skydiver is accelerating or ...

AT the recent Winnipeg meeting of the British Association we presented some results on the terminal velocity of fall of approximately spherical spores, which were not in agreement with Stokes's ...

Many raindrops travel at “super-terminal” velocities, faster than was thought possible. As a result, meteorologists may be miscalculating how much it rains. Previously, it was assumed that all ...
