Electric motor. This consists of a loop of wire that is free to rotate in a magnetic field (yellow arrows).
The loop is attached to a power source (left), which drives a current (blue arrows) around the wire. The loop is connected to the power source through a commutator, a pair of half rings, which reverses the flow of current when the loop...

Rotating triangular prism refracting light.
Materials, such as glass, change the speed of a light beam passing through it (refraction). A beam of white light is consequently split into its constituent colours of varying wavelengths (a rainbow). This process is known as dispersion

Prisms and lenses refracting three rays of light.
From left to right, there is a diverging (biconcave) lens, a converging (biconvex) lens and two triangular prisms. The rays start parallel and diverge after passing through the first lens, then converge after passing through the second....

Weighted spring rising and falling.
This is an example of simple harmonic motion. The weight accelerates downwards under gravity, and is moved back up by the tension in the spring. The velocity of the weight is fastest at the midpoint and slowest (zero) at the top and...
