In this video, we determine the maximum angular speed a coin can have on a rotating turntable without slipping. By analyzing static friction and centripetal force, you’ll learn how rotational dynamics ...

Objective To assess Multi-directional Impact Protection System (MIPS) helmet technology on rotational velocity during head impact using a novel testing method. Design Optimization study. Setting ...

Can we create artificial gravity, or is it still science fiction? In this video, we break the problem down using real physics ...

Probably a better name would be 'rotational mass'. Just like momentum (regular linear kind) is the product of mass and velocity, the angular momentum is the product of the rotational mass and the ...

You need to be in the air long enough for the bike person to make three complete rotations. How do you do that? Go fast, and go high. The higher you go, the longer you are in the air. Suppose you ...

Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more slowly. This happens, thanks to a physics concept known ...
