What is angular momentum? Maybe we should look at linear momentum, typically called simply “momentum,” first. The magnitude of momentum is the product of an object’s mass and velocity.

But what is angular momentum? Let's take a step back. Linear momentum is the product of an object's mass and its velocity (direction and speed). A passenger in a moving car that stops abruptly ...

Since 2006, astrophysicists have shown through computer simulations that when two black holes merge, the gravitational waves emitted during this interaction carry linear momentum with them. This, in ...
