Although these restrictions sound severe, the Bernoulli equation is very useful ... Therefore, to find the velocity V_e, we need to know the density of air, and the pressure difference (p_0 - p_e).

The only difference between velocity and speed is that velocity has a direction, and so is a vector quantity. Average velocity = \(\frac{\text{displacement}}{\text{time}}\) Displacement is the ...

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 ...
