It's important information as it tells you how fast light travels through the material. This can give you an insight into how the angle of refraction of the light is related to the angle ...

The equation is shown below as found in the IB Physcis Data Booklet.

GPE = -GMm / r

Where GPE is gravitational potential energy, G is the gravitational constant, M and m are the mas...

We know that the number of undecayed nuclei, N, is given by N=N₀e^{-lambda t}. From this, by setting N=N₀/2 we know at this point that t= T_0.5 (the half life) and ...

Acceleration is defined as the rate of change of velocity. The important thing to realise here is that velocity is a vector quantity while speed is a scalar one. An object going in circular motion has con...

In a series circuit, the current is the same throughout; the voltage is split among the components (such as LEDs or resistors) in proportion to the resistance of the components (higher resistance means mo...
