• Work done= force x distance
• Kinetic energy= 0.5 x mass x (speed)2
• gravitational potential energy= mass x gravity x height
• power= work done/ time
• power= energy/ time
• efficiency= useful output / input
• charge= current x time
• potential difference= current x resistance
• power= potential difference x current
• power= (current)2 x resistance
• energy transferred= charge flow x potential difference
• density= mass / volume
• W = F s
