Learn how the Standard Model of particle physics is described by a quantum field theory with internal symmetries SU (3) × SU (2) × U (1). Explore the different presentations of the fermion and gauge fields, the chiral and mass eigenstates, and the CKM and PMNS matrices.
Learn about the three physical laws that describe the relationship between the motion of an object and the forces acting on it, formulated by Isaac Newton in 1687. Find out the mathematical definitions, examples, and limitations of these laws in classical mechanics.
A set of equations describing the trajectories of objects subject to a constant gravitational force under normal Earth-bound conditions.Assuming constant acceleration g due to Earth’s gravity, Newton's law of universal gravitation simplifies to F = mg, where F is the force exerted on a mass m by the Earth’s gravitational field of strength g.
