The finest burritos in the world are made in San Francisco’s Mission District. But how can you get a hot & fresh one in New York City in time for lunch? Physics, that’s how. For this very serious and scientific video, we dug a classic...

In this video Paul Andersen explains how the total energy of a system is the combination of kinetic, potential and internal energy of the objects. He then shows you how to calculate the kinetic energy, gravitational potential energy,...

Electric potential can feel abstract, but it doesn’t have to be! In this Flipping Physics lesson, Mr. P and the gang use gravitational potential energy to make sense of electric potential and electric potential energy. You’ll see how...

A launch mishap led to the best experimental confirmation of gravitational redshift.

University of Chicago cosmologist Rocky Kolb describes the history of dark matter: how it was overlooked by most physicists for decades together with current hypotheses of what it might be and experiments to determine which one is valid.

In this video I prove that the work done by the force due to gravity (assumed to be constant and downwards) is equal to the change in gravitational potential energy.
