Physics equations

• Density = mass/volume
• Distance travelled= speed x time
• Acceleration = change in velocity/time
• Kinetic energy = 1/2 mass x (speed)²
• Force = mass x acceleration
• Momentum= mass x velocity
• Work done = force x distance
• Power = work done/time
• Force exerted by a spring = spring constant x extension
• Gravitational force = mass x gravitational field strength
• Gravitational potential energy = mass x gravitational feild strength x height
• Charge flow = current x time
• Potential difference = current x resistance
• Energy transferred = charge x potential difference
• Power = current² x resistance
• Energy transferred = power x time
• Wave speed = frequency x wave length
• Efficiency = useful out energy transfer / input energy transfer
• Pressure = force normal to the surface /area of that surface
• Moment of a force = force x distance (normal to direction )
