IB Physics - 6.2 - Gravitational Force and Orbital Velocity

An IB/A-level Physics video explaining the difference between gravitational field strength and gravitational force, and how to calculate each. Also, a derivation of the orbital velocity equation.

That’s cool. But did you know that the trajectory of the gravitational force between the earth and wind, combined with the altitudic status of the stratosphere with the very little density of the air, at a very high falling rate causes the surpassing of the ruptured speed of sound?

Nice. They only correction I would suggest is the man next to the African elephant will most likely be in a state of rapid acceleration away from the elephant 😂
