Physics quantities

Hint

Answer

The rate change of velocity, a vector quantity

The maximum displacement from the equilibrium position (waves)

The charge stored per unit potential difference across a capacitor

Defined as the energy transferred from chemical to electrical energy per unit charge

The lowest frequency at which an object can vibrate

The average time taken for half the number of active nuclei in a sample of an isotope to decay

The strength of a magnetic field

The difference between the displacements of particles along a wave, or the difference between the displacements of particles on different waves

Defined as the energy transferred from electrical energy to other forms per unit charge

Hint

Answer

A property of a component calculated by dividing the potential difference across it by the current in it

The energy required per unit mass to change the temperature by 1K

The extension per unit length, a dimensionless quantity

Force per unit cross-sectional area

The constant speed reached by an object when the drag force (and upthrust) is equal and opposite to the weight of the object

The product of one of the forces of a couple and the perpendicular distance between the forces

The minimum energy needed to remove a single electron from the surface of a particular metal

The ratio of tensile stress to tensile strain when these quantities are directly proportional to each other
