This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to ...

Cats falling from super-high heights have a greater chance of survival than low-rise falls. That depends on two things: air resistance and apparent weight.

In the absence of air resistance, an object falling near the surface of the Earth should trace out a parabola, with an acceleration of 9.8 m/s 2 downward.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Thus, falling from high floors should have more unpleasant consequences than from low floors. But this way of thinking about the feline free-fall ignores air resistance.

All objects in the absence of air resistance (friction) fall at the same rate regardless of their mass. Due to gravity the speed of an object dropped from rest from a height will increase at the ...

Now, how is a pulse of light sent by someone falling into a black hole different from the gravitational waves emitted during a merger?
