What is the equation for Weight?
Weight = mass x gravitational field strength
This equation calculates the force of gravity acting on an object.
How is Work done calculated?
Work done = force x distance
Work done measures the energy transferred when a force moves an object over a distance.
What is the equation for Force applied to a spring?
Force = spring constant x extension
This equation describes Hooke’s Law, which relates the force exerted by a spring to its extension.
What is the formula for Distance?
Distance = speed x time
This equation calculates how far an object travels over a period of time at a constant speed.
How is Acceleration defined?
Acceleration = change in velocity
Acceleration measures how quickly an object’s velocity changes over time.
What is the Resultant force equation?
Resultant force = mass x acceleration
This equation is derived from Newton’s second law of motion.
How is Momentum calculated?
Momentum = mass x velocity
Momentum is a measure of the motion of an object and is conserved in isolated systems.
What is the formula for Kinetic energy?
Kinetic energy = 0.5 x mass x (speed)?
Kinetic energy represents the energy of an object due to its motion.
How do you calculate Gravitational potential energy?
Gravitational potential energy = mass x gravitational field strength x height
This energy is due to an object’s position in a gravitational field.
What is the equation for Power?
Power = energy transferred / time
Power measures the rate at which energy is transferred or converted.
How is Efficiency defined?
Efficiency = useful energy out / total energy in
Efficiency measures how effectively energy is converted from one form to another.
What is the equation for Wave speed?
Wave speed = frequency x wavelength
This equation relates the speed of a wave to its frequency and wavelength.
How do you calculate Charge?
Charge = current x time
This equation determines the amount of electric charge that flows over time.
What is the formula for Potential difference?

This equation relates voltage to the current flowing through a conductor and its resistance.
How is Power related to Potential difference and current?
Power = potential difference x current
This equation calculates the electrical power consumed in a circuit.
What is the equation for Energy transferred?
Energy transferred = charge x potential difference
This equation shows how energy is transferred in an electrical circuit.
How is Density calculated?
Density = mass / volume
Density is a measure of how much mass is contained in a given volume.
