For the constant positive velocity graphs and the constant positive acceleration graphs, the initial displacement is zero and the initial velocity is zero. For the constant negative acceleration ...

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 ...

Velocity-time graphs show how the velocity (or speed ... axis shows the speed is zero, meaning that the vehicle has stopped, or is stationary. The area under the graph is the distance moved.

If the velocity is zero, so is the pressure it exerts on the medium (e.g. air) around it. Velocity (and therefore pressure) is greatest mid-way between the maximum displacement of the vibrating body, ...
