AQA GCSE Physics Equations

What is the equation that links gravitational field strength (g), mass (m) and weight (W)?

• Weight = Mass x Gravitational Field Strength, or W=mg

• Weight = Mass / Gravitational Field Strength, or W=m/g

• Weight = Gravitational Field Strength / Mass, or W=g/m

What is the equation that links distance (s), force (F) and work done (W)?

• Work Done = Force x Distance, or W=Fs

• Work Done = Force / Distance, or W=F/s

• Work Done = Distance / Force, or W=s/F

What is the equation that links distance from the pivot (d), force (F), and moment of a force (M)?

• Moment of a Force = Force x Distance From The Pivot, or M=Fd

• Moment of a Force = Force / Distance From The Pivot, or M=F/d

• Moment of a Force = Distance / Force From The Pivot, or M=d/F

What is the equation that links distance (s), time (t) and velocity (v)?

• velocity = time x distance, or v=ts

• velocity = distance / time, or v=s/t

• velocity = time / distance, or v=t/s

What is the equation that links acceleration (a), change in velocity (Δv) and time (t)?

• Acceleration = Change in Velocity x Time, or a=Δv x t

• Acceleration = Change in Velocity / Time, or a=Δv/t

• Acceleration = Time / Change in Velocity, or a=t/Δv

What is the equation that links acceleration (a), mass (m), and resultant force (F)?

• Resultant Force = Mass x Acceleration, or F=ma

• Resultant Force = Mass / Acceleration, or F=m/a

• Resultant Force = Acceleration / Mass, or F=a/m

What is the equation that links mass (m), momentum (p), and velocity (v)?

• Momentum = Mass x Velocity, or p=mv

• Momentum = Mass / Velocity, or p=m/v

• Momentum = Velocity / Mass, or p=v/m

What is the equation that links frequency (f), wavelength (λ) and wave speed (v)?

• Wave Speed = Wavelength x Frequency, or v=λf

• Wave Speed = Wavelength / Frequency, or v=λ/f

• Wave Speed = Frequency / Wavelength, or v=f/λ

What is the equation that links density (ρ), mass (m) and volume (V)?

• Density = Volume x Mass, or ρ=Vm

• Density = Mass / Volume, or ρ=m/V

• Density = Volume / Mass, or ρ=V/m

What is the equation that links area, force and pressure

• pressure = force x area

• pressure = force/area

• pressure = area/force

• force = pressure/area
