⚛️ Physics: Core Concepts

Inertia

Tendency of objects to resist changes in motion

Velocity

Speed of an object in a specific direction

Acceleration

Rate of change of velocity over time

Momentum

Mass in motion, product of mass and velocity

Force

A push or pull causing acceleration

Gravity

Force attracting objects with mass toward each other

Friction

Force resisting motion between two surfaces

Energy

Capacity to do work or cause change

Kinetic Energy

Energy an object has due to motion

Potential Energy

Stored energy based on position or state

Work (Physics)

Force applied over a distance

Power (Physics)

Rate at which work is done

Newton's First Law

Object stays at rest or in motion unless acted on

Newton's Third Law

Every action has an equal opposite reaction

Wavelength

Distance between two consecutive wave peaks

Frequency

Number of wave cycles per second

Amplitude

Maximum height of a wave from rest

Electric Current

Flow of electric charge through a conductor

Voltage

Electric potential difference driving current

Resistance (Electricity)

Opposition to electric current flow

Magnetic Field

Region where magnetic force is detectable

Thermodynamics

Study of heat, energy, and work

Entropy

Measure of disorder in a system

Refraction

Bending of light passing between materials

Half-Life

Time for half a radioactive sample to decay
