Physics

Items

• core

  The central part of an object.
• cosmology

  The study of the universe as a whole, how it began, how it changes, and what it’s made of.
• cosmos

  The entire universe; everything that exists, including stars, planets, galaxies, and all space and time.
• covalent

  A type of chemical bond where atoms share electrons to stick together.
• crest

  The highest point of a wave.
• critical point

  An important point where something changes suddenly or drastically.
• cube

  3D shape with six equal square faces — like a dice. All its edges are the same length.
• curl

  A measure of the rotation or circulation of a vector field at a point.
• current

  The flow of electric charge through a conductor, such as a wire.
• curvature

  Measures how much a curve or surface bends at a particular point.
• cycle

  A process or event that repeats itself over and over.
• cyclotron

  A type of particle accelerator that uses a combination of a constant magnetic field and an alternating electric field to accelerate charged particles (like protons or ions) in a spiral path.
• cylinder

  3D shape with two parallel circular bases connected by a curved surface — like a can or a tube.
• damp

  To reduce the strength or intensity of something, like a vibration or sound.
• decay

  Process by which an unstable system loses energy, particles, or changes state over time, often spontaneously.
• decelerate

  To slow down or reduce the speed of an object.
• deformation

  Change in shape or size of an object due to an applied force or stress.
• density

  Physical property that describes how much mass is packed into a given volume of a substance.
• dependent

  Something or a parameter that changes because of something else.
• depth

  Distance from the top surface down to the bottom of something.
• derive

  To find or get a formula or result by using known facts, principles, or equations through logical steps.
• destructive interference

  Occurs when two or more waves overlap out of phase, meaning the crest of one wave aligns with the trough of another. This causes the waves to cancel each other out, reducing the overall amplitude.
• deuterium

  A stable isotope of hydrogen, often called heavy hydrogen.
• deviate

  To move away or change from a normal path, direction, or expected value.
• device

  Any piece of equipment or tool designed to perform a specific function or task.
