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 as level physics textbook pdf 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. Basic principles of electrostatics are introduced in order to explain how objects become charged and to describe the effect of those charges on other objects in the neighboring surroundings.
Charging methods, electric field lines and the importance of lightning rods on homes are among the topics discussed in this unit. The flow of charge through electric circuits is discussed in detail. The variables which cause and hinder the rate of charge flow are explained and the mathematical application of electrical principles to series, parallel and combination circuits is presented.
The nature of sound as a longitudinal, mechanical pressure wave is explained and the properties of sound are discussed. Wave principles of resonance and standing waves are applied in an effort to analyze the physics of musical instruments. Color perception is discussed in detail.
