Physics

an electrical component designed to limit or control the flow of electric current in a circuit, typically by providing resistance

In electronic circuits, resistors are commonly used to regulate the flow of current and protect sensitive components.

an electric device that is used to accumulate electric charge

the branch of physical science that deals with the relationships between heat, work, and energy, particularly the principles governing the conversion of various forms of energy

The first law of thermodynamics, also known as the law of conservation of energy, states that energy cannot be created or destroyed, only transferred or converted from one form to another.

(physics) an invisible substance that makes up most of the universe's mass, detectable only through its gravitational effects

Dark matter is a form of matter that does not emit, absorb, or reflect light, making it invisible and detectable only through its gravitational effects.

a fundamental particle of light that carries electromagnetic energy and exhibits both particle-like and wave-like properties

Photons are the quanta of electromagnetic radiation, including visible light, radio waves, and X-rays.

the specific number of waves that pass a point every second

In physics, frequency is measured in hertz, which represents the number of waves passing a point per second.

the distance between a point on a wave of energy and a similar point on the next wave

In physics, wavelength is the distance between two consecutive peaks (or troughs) of a wave.

expression of something without the use of words

His face was a reflection of sorrow.

the force or energy that propels a process, idea, or endeavor, enabling it to continue moving, progressing, or gaining strength

The campaign gained momentum after the first success.

a tendency toward inactivity and stability

Cultural inertia can impede the acceptance of new ideas in a traditional society.

(physics) the back-and-forth motion of an object between two end points

Pendulums have proven useful for studying simple harmonic oscillation and modeling more complex periodic motions in dynamic systems.

a small semiconductor device, used in television and radio sets, able to amplify or rectify an electric current

an electronic device with two terminals, typically allowing the flow of current in one direction only

an electronic component that stores energy in a magnetic field when an electric current flows through it; typically consists of a coil of wire

Inductors are fundamental components in electronic circuits, storing energy in a magnetic field and releasing it when the current changes.

the study of the behavior of air as it interacts with solid objects, particularly the flow of air around and through objects, and the effects of this interaction on the objects

Aerodynamics is essential in designing efficient aircraft wings, optimizing their shape for lift and minimizing drag during flight.
