Learn how to calculate gravitational forces on a spacecraft from Earth and the Moon! Step-by-step physics tutorial covering force equations, vectors, and practical examples for orbital mechanics.

Gravity is the force of attraction between two objects. Its effects play an interesting role between a giant planet such as Jupiter or Saturn and their numerous moons — for instance, the Galilean ...

Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under ...

There are quite a few fundamental constants. These are things like the speed of light (c) the charge on an electron (e), and the Planck constant (h). These constants are determined with some type of ...

China has unveiled a new hypergravity research machine capable of generating forces nearly two thousand times stronger than ...

Most of us take gravity as an assumed part of our living realities, but why? Most of us take gravity as an assumed part of our living realities, but why? Basic physics introduces us to the concept of ...
