Classical mechanics (movement)
General Form: $$A = B \times C$$ use the "algebra pyramid" to rearrange the equation respectively


 * $$force = mass \times acceleration$$
 * $$weight = mass \times acceleration_{duetogravity}$$
 * $$density = \frac{mass}{volume}$$
 * $$acceleration = \frac{v_f-v_i}{t_f-t_i}$$
 * $$velocity = \frac{distance}{time}$$
 * $$distance = \frac{acceleration_{duetogravity} \times time ^ 2}{2}$$ (for something that is falling. usually the y component)
 * $$displacement = Original velocity \times time + \frac{1}{2} acceleration \times (time ^ 2)$$

Kinetic and potential energy

 * $$kineticenergy = \frac{mass \times velocity ^ 2}{2}$$
 * $$potentialenergy = mass \times acceleration_{duetogravity} \times h$$
 * $$momentum = mass \times velocity$$
 * $$I = F \times T$$

Waves
Speed = Distance/Time s = d/t Velocity = Frequency * Lambda v=f*ʎ

Electromagnetics (electricity)

 * $$power = voltage \times current$$
 * $$current = \frac{voltage}{resistance}$$
