What is the equation for gravitational potential energy (GPE) as per the AQA GCSE Physics specification?

• GPE = mass × gravitational field strength × height

• GPE = mass × speed^2

• GPE = 1/2 × mass × speed^2

• GPE = mass × gravitational field strength / height

According to the AQA GCSE Physics specification, how is power calculated?

• power = work done / time taken

• power = current × potential difference

• power = current^2 × resistance

• power = energy transferred / charge

What is the correct expression for density as given in the AQA GCSE Physics exam?

• density = mass / volume

• density = mass × volume

• density = mass / area

• density = mass + volume

In the context of waves, what is the equation for wave speed?

• wave speed = frequency × wavelength

• wave speed = frequency / wavelength

• wave speed = wavelength / frequency

• wave speed = frequency + wavelength

How is pressure calculated in the context of forces, as per the AQA GCSE Physics specification?

• pressure = force / area of that surface

• pressure = force × area of that surface

• pressure = force + area of that surface

• pressure = force - area of that surface

What is the equation for calculating the moment of a force?

• moment = force × distance (perpendicular to the direction of the force)

• moment = force / distance (perpendicular to the direction of the force)

• moment = force + distance (perpendicular to the direction of the force)

• moment = force - distance (perpendicular to the direction of the force)

What is the formula for calculating Gravitational Potential Energy (E_p)?

• E_p = 1/2 x mass x velocity^2

• E_p = mass x specific heat capacity x change in temperature

• E_p = mass x gravitational field strength x height

• E_p = mass / (gravitational field strength x height)

Which type of energy is increased when an object is heated?

• Gravitational Potential Energy

• Kinetic Energy

• Elastic Energy

• Thermal Energy
