Editor's Note: The Hyperloop is a totally imaginary transportation device that has captivated entrepreneur Elon Musk, who keeps talking about it. First imagined at least 100 years ago, it would ...

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.

Learn the key physics definitions of position, displacement, velocity, and acceleration explained clearly and simply. This quick breakdown helps build a strong foundation for understanding motion in ...

Disturbance rejection, like command tracking, is usually expressed graphically. The graphs, called disturbance rejection plots, show the effect of PIV gains on disturbance torque applied to the shaft ...

Acceleration close accelerationThe rate of change in speed (or velocity) is measured in metres per second squared. Acceleration = change of velocity ÷ time taken. is the rate of change of velocity. It ...
