Half-life – the property of various material objects to acquire different accelerations under the same external influences from other bodies.

Inertia– the tendency of a body to preserve its state of rest or uniform motion unless acted upon by an external force

Ions - electrically charged atoms or groups of atoms formed when electrons are lost or attached.

Joule – the derived SI unit of work or energy;

Kinetic energy – the energy of motion of a body, equal to the work it would do if it were brought to rest.

Luminescence – a non-thermal glow of a substance that occurs after it absorbs the excitation energy.

Material point – a body whose dimensions can be neglected in the conditions of this task.

Mass – a scalar quantity that is a measure of inertia and a measure of gravity of material objects.

Oscillations – movements characterized by varying degrees of repeatability over time.

Pendulum – a solid body that oscillates around a fixed point or axis under the action of applied forces.

Photoelectric effect – the emission of electrons by a substance under the influence of electromagnetic radiation.

Phosphorescence – luminescence that lasts for a considerable time after the termination of its excitation.

Polarization – a set of phenomena in which the property of the transversity of light waves is manifested.

Polarizer – a device that turns an unpolarized wave into a polarized one.

Positron – an elementary particle with a mass equal to the mass of an electron, a positive elementary electric charge.

Quarks – hypothetical particles, of which, as it is assumed, all known hadrons can consist.
