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 ...

Note that since the top contact point of the disk rolls without slipping on the upper fixed surface, this contact point has zero velocity. In addition, the horizontal component of acceleration of that ...

For a steady flow through a control volume with many inlets and outlets, the net mass flow must be zero, where inflows are negative and outflows are positive. A streamline is a line that is tangential ...

Since the velocity at the stagnation point is zero, The dynamic pressure is not really a pressure at all: it is simply a convenient name for the quantity (half the density times the velocity squared), ...

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