Gravitational force is the attractive force between two masses due to their mass and the distance between them. According to Newton's law of universal gravitation, every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This force is responsible for phenomena such as the Earth's gravitational pull on objects and the motion of planets around the sun.
 Sir Isaac Newton formulated three laws of motion, which are fundamental principles in classical mechanics.  First Law (Law of Inertia): An object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by a net external force. In simpler terms, objects resist changes in their state of motion. Second Law (Law of Acceleration): The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The direction of the acceleration is in the direction of the net force. Mathematically,  F=m×a, where  F is the force,  m is the mass, and  a is the acceleration. This law explains how the velocity of an object changes when subjected to an external force. Third Law (Action and Reaction): For every action, there is an equal and opposite reaction. If object A exerts a force on object B, then object B simultaneously exerts a force of equal magnitude in t...
