Study Notes

Motion

Uniform motion occurs when an object is moving with constant velocity.
An object must have no net force acting on it to have a constant velocity.
The term "uniform motion" describes the motion of an object moving with constant velocity.
Rectilinear motion occurs when an object is moving in a straight path with a constant speed.

Quantum Mechanics

The probability of a measurement outcome is calculated by applying the Born rule to the wave function of the system.
The Schrödinger equation relates the wave function of a quantum system to its potential energy.
The uncertainty principle states that it is impossible to know certain properties of a quantum system, such as position and momentum, simultaneously with infinite precision.
Wave-particle duality is the phenomenon where quantum objects, such as electrons, can exhibit both wave-like and particle-like behavior.
A key difference between quantum mechanics and classical physics is the role of probability in predicting measurement outcomes.
Max Planck's solution to the black-body radiation problem in 1900 introduced the concept of quantized energy, contributing to the development of quantum mechanics.
Key contributors to the full development of quantum mechanics in the mid-1920s included Niels Bohr, Louis de Broglie, Erwin Schrödinger, and Werner Heisenberg.
The state of a quantum mechanical system is described by a wave function that encodes all possible information about the system.
Entanglement is a phenomenon where two or more quantum systems become correlated in such a way that the state of one system cannot be described independently of the others.
Entanglement plays a crucial role in communication protocols, such as quantum cryptography and quantum teleportation.
Bell's theorem demonstrates that any hidden-variable theory, which attempts to explain entanglement through classical means, must satisfy certain statistical constraints.
