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 ...

It travels \(\frac{1}{2} \times 4 \times 8 = 16~m\). Between 4 and 7 seconds: the object is travelling at a constant velocity of 8 m/s. It travels \(3 \times 8 = 24~m\). Between 7 and 10 seconds ...

points 1 and 2 lie on a streamline, the fluid has constant density, the flow is steady, and there is no friction. Although these restrictions sound severe, the Bernoulli equation is very useful, ...
