Physics

• Power = Energy / time
• Newtons second law states that the rate at which an object's momentum changes is equal to the net external force acting on it.
• Energy transferred = power / time
• Charge = current / time
• Potential difference = current x resistance
• Acceleration = velocity / time
• Force = spring constant x extension
• Pressure = force / area
• Work done = force x distance moved
• Weight = mass x gpe
