Classical mechanics is a branch of physics that studies the motion of particles and systems under the influence of forces.
Gravitation is a fundamental force of nature that causes massive objects to attract each other. It is responsible for the motion of planets, stars, and galaxies.
According to Newton's law of gravitation, the force of attraction between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them. This means that the larger the masses of two objects and the closer they are, the stronger the gravitational force between them.
Simple harmonic motion is a type of periodic motion in which a particle moves back and forth along a straight line with a constant amplitude and a constant period. It is characterized by a restoring force that is directly proportional to the displacement of the particle from its equilibrium position.
SHM can be observed in various systems, such as a pendulum, a mass attached to a spring, or the motion of a vibrating guitar string. It also has practical applications in fields like engineering, as it can be used to design and analyze systems that exhibit simple harmonic motion.
