Our physics expert picks his top-five equations, plus a scheme to supply US power needs with a bucket of baseballs. Thanks, ...

Although these restrictions sound severe, the Bernoulli equation is very useful, partly because it is very simple to use and partly because it can give great insight into the balance between pressure, ...

The wavelength equation is v = λ x f, where λ is the wavelength, v is the wave velocity and f is the wave's frequency. This formula highlights the inverse relationship between wavelength and ...

The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time. \(\text{Gradient} = \frac{{change\,in\,velocity ...

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 ...

Bernoulli’s Equation formula is a relation between pressure ... p is the pressure exerted by the fluid, v is the velocity of the fluid and h is the height of the container.
