A force is a push or pull that can cause an object to move, stop, or change direction. It is a fundamental concept in physics that explains how objects interact with each other.

Frequency refers to how often something happens in a specific period of time. In physics, it is commonly used to describe waves, indicating how many cycles occur in one second.

Friction is a force that opposes the motion of objects sliding or rolling against each other. It acts in the opposite direction to movement and is essential for everyday activities like walking or driving.

It is a theory of gravitation developed by Albert Einstein that describes how massive objects warp space and time around them. This warping affects the motion of other objects, leading to the phenomenon we perceive as gravity.

A gravitational field is a region around a mass where other masses experience a force of attraction. It describes how gravity affects objects within its vicinity, influencing their motion and behavior.

It is a force that pulls objects toward each other, giving weight to physical objects and keeping planets in orbit. Essentially, gravity is what keeps us grounded on Earth and governs the motion of celestial bodies in space.

Heat is the form of energy that is transferred between objects due to a temperature difference. It moves from warmer objects to cooler ones until thermal equilibrium is reached.

The Higgs Boson is a fundamental particle in physics that gives mass to other particles. It is associated with the Higgs field, which permeates the universe and interacts with particles to provide them with mass.

The Ideal Gas Law is a mathematical equation that describes the relationship between pressure, volume, temperature, and the number of moles of a gas. It combines several gas laws into one formula, allowing us to predict how gases will behave under different conditions.

Impulse is a concept in physics that describes the change in momentum of an object when a force is applied over a certain time period. It is calculated as the product of the force and the time duration during which the force acts. Understanding impulse helps explain how objects move and change speed.

Inductance is a property of an electrical circuit that allows it to store energy in a magnetic field when an electric current flows through it. It is measured in henries and is crucial in understanding how electrical devices work, especially in circuits involving coils or inductors.

Interference is a phenomenon that occurs when two or more waves overlap, resulting in a new wave pattern. This can lead to areas of increased intensity, called constructive interference, or decreased intensity, known as destructive interference.

This is the energy an object has due to its motion. The faster an object moves or the heavier it is, the more kinetic energy it has.

A lepton is a fundamental particle in physics that does not experience strong interactions. They are part of the Standard Model of particle physics and include particles like electrons and neutrinos.

A magnetic field is an invisible area around a magnet where magnetic forces can be felt. It is created by moving electric charges and affects other magnets and charged particles within its range.

Mass is a measure of the amount of matter in an object, typically measured in kilograms or grams. It determines how much an object resists acceleration when a force is applied to it.
