If you are having any suggestion for the improvement, your are welcome. Physics deals with the study of basic laws of nature related to matter, energy and their manifestation in different phenomena. It also deals with static and dynamic systems.
The basic laws of physics are universal and apply in widely different contexts and conditions. The gravitational force, electromagnetic force, strong nuclear force and weak nuclear force are the four fundamental forces in nature. The attempts towards the unification of forces are going on. The physical quantity that remains unchanged with time is called conserved quantity.
The laws of conservation of energy, charge, linear momentum and angular momentum are considered as the fundamental laws of physics. The motion of objects in one-dimension are described using word, diagrams, numbers, graphs, and equations. Newton’s three laws of motion are explained and their application to the analysis of the motion of objects in one dimension is discussed. Vector principles and operations are introduced and combined with kinematic principles and Newton’s laws to describe, explain and analyze the motion of objects in two dimensions.
Applications include riverboat problems, projectiles, inclined planes, and static equilibrium. The impulse-momentum change theorem and the law of conservation of momentum are introduced, explained and applied to the analysis of collisions of objects. Newton’s Universal Law of Gravitation is then presented and utilized to explain the circular and elliptical motion of planets and satellites. The distinction between heat and temperature is thoroughly explained. Methods of heat transfer are explained.
