EQUATIONS
Distance = Speed x Time
Acceleration = (Final Velocity - Initial Velocity) / Time Taken
Force (N) = Mass (Kg) x Acceleration (m/s2)
Weight = Mass (Kg) x Gravity (N)
Kinetic Energy = ½ x Mass (Kg) x Velocity2 (m/s)
Efficiency = (Useful Energy Output / Total Energy Input) x 100
Gravitational Potential Energy = Mass (Kg) x Gravity (N) x Height (m)
Work Done (J) = Force (N) x Distance (m)
Power (W) = Work Done (J) / Time (s)
Acceleration = Change in Velocity / Change in Time = Rise / Run
Hooke’s Law:
Force (N) = Constant (N/m) x Extension (m)
Refractive index = sin(i) / sin(r)
Density = Mass / Volume
Charge (Q) = Current (I) x Time (t)
Resistance = Voltage (V) / Current (I)
Energy = Voltage (V) x Current (I)
Magnification = Image Size / Actual Size
