Linear momentum from mass and velocity (p = m·v).

The electrostatic force between two point charges. Charges are in microcoulombs (µC).

Power and resistance from voltage and current (P = V × I).

The wavelength of a wave from its frequency, using the speed of light.

Mechanical work done by a force over a distance (W = F × d).

Power as work done divided by the time taken (P = W ÷ t).

Pressure as force divided by area, in pascals and kilopascals.

Newton's gravitational force between two masses (F = G·m₁·m₂/r²).

Find voltage and power from current and resistance.

Find force from mass and acceleration (Newton's second law).

Find kinetic energy from mass and velocity.

Find gravitational potential energy from mass and height.

Find acceleration from the change in velocity over time.
