Physics Equations

• Weight = Mass x Gravitational Field Strength

  W = m g
• Work done = force x distance
• Force applied to spring = Spring constant x Extension
• Moment = force x distance
• Pressure = Force / Area
• Distance = Speed x Time
• Acceleration = Change in velocity / Time taken
• Resultant force = mass x acceleration
• Momentum = mass x velocity
• Kinetic energy = 0.5 x mass x velocity^2
• Gravitational potential energy = weight x height

  
  

  or

  
  

  gravitational potential energy = mass x gravitational field strength x height
• Power (energy) = energy transferred / time
• Power (work done) = work done / time
• Wave speed = frequency x wavelength
• Charge flow = current x time

  Q=It
• Potential difference = current x resistance

  V=IR
• Power (potential difference) = potential difference x current
• Power (current) = current^2 x resistance
• Energy transferred (Power) = Power x time
• Energy transferred (Charge flow) = charge flow x potential difference
• Density = Mass / Volume
• pressure = height of column x density of liquid x gravitational field strength
