Particle Accelerator
A particle accelerator is a type of machine that accelerates charged particles, such as protons or electrons, to high speeds, often near the speed of light, allowing them to collide with other particles or targets for scientific research. These collisions help physicists study fundamental forces and particles at a subatomic level.They are used in various applications, including medical therapies, materials science, and fundamental physics experiments.
Neutron
It weighs \(1.675 \times 10^{-27}\) kilograms, which is slightly heavier than a proton. [1, 2]A subatomic particle found in the nucleus of an atom, with no electric charge.
Atom
The basic unit of matter, composed of protons, neutrons, and electrons, which defines the chemical properties of elements.
Anitmatter
Antimatter is a form of matter composed of antiparticles, which have the exact same mass as standard subatomic particles but carry opposite electric charges and quantum properties. For example, the antiparticle of a negatively charged electron is a positively charged positron, while the antiparticle of a proton is a negatively charged antiproton.
When a particle of regular matter interacts with its corresponding antiparticle, they undergo annihilation. During annihilation, both particles are destroyed, converting their combined mass entirely into high-energy radiation, primarily in the form of photons (gamma rays). Antimatter is produced naturally in tiny amounts through cosmic ray collisions and radioactive decay, as well as artificially in high-energy physics laboratories. It also has practical applications in medical imaging, such as Positron Emission Tomography (PET) scans.
Photon
A quantum of electromagnetic radiation, having zero mass and no electric charge, that carries energy. Photons are the force carriers of the electromagnetic force, mediating electromagnetic interactions.
Nuclear physics
The branch of physics that studies atomic nuclei, their interactions, and the forces that govern the behavior of nuclear particles, including processes like nuclear decay and fusion. Nuclear physics also explores applications, such as nuclear energy and medical technologies like radiation therapy.
Pendulum Arch
A regular periodic motion of a mass attached to a string or rod, where the mass swings back and forth under the influence of gravity, demonstrating simple harmonic motion. The time period of a pendulum depends on its length and the acceleration due to gravity, and it is independent of the mass of the pendulum.
Quantum Entanglement
A physical phenomenon where particles become correlated in a such a way that the state of one particle instantly influences the state of another, regardless of the distance separating them. This phenomenon is central to quantum mechanics and has implications for quantum computing and information theory.
