Laws of Motion:These are three fundamental principles formulated by Isaac Newton that describe the relationship between a body and the forces acting upon it.
Universal Gravitation: This is Newton's law that states every particle attracts every other particle with a force directly proportional to their masses and inversely proportional to the square of the distance between them.
Calculus:This mathematical tool developed by Newton (and independently by Leibniz) is used to study rates of change and motion. It plays a crucial role in many areas of physics.
