Physics

Items

• diamagnetism

  A type of magnetism where materials create a weak, negative response to an external magnetic field, i.e., they are repelled by it.
• diameter

  The distance across a circle, passing through the center from one side to the other.
• diatomic

  Molecules composed of two atoms, which may be of the same or different elements.
• dielectric

  An insulating material that doesn’t conduct electricity but can store electric energy when placed in an electric field.
• differential

  A very small change in a quantity, often used to study how things change continuously.
• differentiate

  To find the rate at which something changes, usually by using calculus.
• differentiate

  To identify the differences among things.
• diffraction

  A wave phenomenon where waves bend around obstacles or spread out after passing through narrow openings.
• diffuse

  Describes the way light or other waves scatter in many directions rather than reflecting or transmitting in a single, clear path.
• diffusion

  The process by which particles spread out from an area of higher concentration to an area of lower concentration, moving randomly until they are evenly distributed.
• digit

  Any single number from 0 to 9.
• dimension

  A direction or measurement of space, like length, width, and height. Time is also considered a dimension in spacetime.
• diode

  An electronic component that allows current to flow in only one direction, like a one-way valve for electricity.
• dipole (electric)

  A pair of equal and opposite electric charges that are separated by a small distance.
• dipole (magnetic)

  A pair of equal and opposite magnetic poles separated by a small distance.
• direction

  The line or path along which something moves, points, or faces.
• disc

  A disc is a flat, round shape like a circle, but includes everything inside it, like a flat, solid plate.
• displacement

  A vector quantity that describes the shortest straight-line distance and direction from an object's initial position to its final position.
• dissipation

  The process by which energy (usually mechanical, electrical, or thermal) is lost, spread out, or transformed into less useful forms, often as heat.
• distance

  The total length between two points, no matter the direction.
• diverge

  To move or spread apart from a common point or path.
• divert

  To change the direction of something, like bending or redirecting the path of light, water, or a moving object.
• domain

  The set of all possible input values for a function or system.
• dual

  Having two parts, aspects, or functions.
• ductile

  Material’s ability to stretch or deform without breaking, especially when pulled into a wire, it’s a key property in materials science and physics.
