The speed of an object does not require a direction to be considered, it simply has a value and unit, for example, 27 \(m\,s^{-1}\). Velocity is a vector quantity which requires a value, unit and ...

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.

If the angular velocity of a link in a mechanism is zero, does this imply that the angular acceleration of that link is also zero? The short answer to that question is NO. If ω(t) represents the ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. This helps, sort of, but as more numbers get thrown around, it can get ...

There are plenty of technical terms in Umamusume: Pretty Derby, and since players are constantly bombarded by text and numbers in this game, it's quite easy to get lost or confused. Acceleration and ...

Bobsled, luge and skeleton athletes descend twisting, steep tracks at speeds upward of 80 mph (130 kmh). Julian Finney/Getty Images Speed alone may be the factor that draws many sports fans to the ...
