Without a fundamental understanding of mechanics, one cannot effectively study more advanced topics in physics. It is the groundwork for analyzing forces, motion, and energy transformations.
Mechanics is one of the most fundamental branches of physics, dealing with the behavior of physical bodies when subjected to forces or displacements. It provides the principles that govern the motion of objects, from the very small, like atoms, to the very large, like planets and galaxies.
Classical mechanics, also known as Newtonian mechanics, is the study of the motion of objects that are much larger than atoms and move at speeds much slower than the speed of light. It relies on concepts such as force, mass, and acceleration, as defined by Isaac Newton's laws of motion.
Quantum mechanics is the branch of mechanics that deals with the behavior of particles on a very small scale, such as atoms and subatomic particles. It introduces concepts like wave-particle duality and uncertainty, which are not present in classical mechanics.
Relativistic mechanics extends classical mechanics to include high-velocity scenarios near the speed of light, as described by Einstein's theory of relativity. It accounts for the effects of time dilation and mass-energy equivalence.
