equations

• kinetic energy= 1/2 x mass x speed squared
• gravitational potential= mass x gravitational speed length x height
• efficiency= useful power out/ total power in
• the 2 power equations?

  p=work done/ time taken and energy transferred/time taken
• density= mass/volume
• charge flow = current x time
• potential difference= current x resistance
• pressure= force/ area
• magnification= image height/ object height
• weight= gravitational field strength x mass
• work done= force x distance
• force= spring constant x extension
• moment of a force= force x distance
• distance travelled = speed x time
• accelleration= change in velocity/ time taken
• resultant force= mass x acceleration
• wave speed= frequency x wavelength
