physics equations

• weight = mass x gravitational field strength
• work done = force x distance
• force applied to a spring = spring constant x extension
• moment of a force = force x distance
• pressure = force / area
• distance = speed x time
• resultant force = mass x acceleration
• momentum = mass x velocity
• kinetic energy = 0.5 x mass x speed^2
• gravitational potential energy = mass x gravitational field strength x height
• power = energy / time
• power = work done / time
• efficiency = useful output energy transfer / total input energy transfer
• efficiency = useful power output / total power input
• wave speed = frequency x wavelength
• charge flow = current x time
• potential difference = current x resistance
• power = potential difference x current
• power = current^2 x resistance
• energy transferred = power x time
• energy transferred = charge flow x potential difference
• density = mass / volume
