This comprehensive course covers Newton's Laws of Motion. The course is taught by Dr.E, an award winning instructor with over 15 years of teaching and tutoring experience. The course combines lectures that summarize the important concepts and tutorials that will guide you and help you develop a problem solving strategy. You'll learn how to apply Newton's laws to study particles in equilibrium and the dynamics of particles when forces are acting on them. Topics include in this class are:1) Vector ReviewReview vector addition and subtraction,Adding vectors using graphical methodsAdding vector using components2) Newton's First LawProblem solving strategiesFree-body diagramsExample problems for objects in equilibrium.3) Forces Review of push and pull forcesUnderstanding the force of gravityThe difference between weight and massFriction Forces: Kinetic vs StaticNormal ForcesTension ForcesForces due to a spring: Hooke's Law4) Newton's 2nd and 3rd LawDrawing Free Body DiagramsCalculating accelerationAction-reaction pairsStrategy to solve problemsExample problems5) Mastering Problems a) Elevator Problems Drawing Free body diagramsCalculate acceleration and effective mass b) Block on a slopeUnderstanding the Free Body DiagramCalculating AccelerationWhat happens when we add friction - kinetic and static frictionc) Pulleys and SpringsLearn how to solve dynamic problems that contain pulleysAtwood's machine: Calculating acceleration and TensionDealing with springs in series and in parallel5) Dynamics of Uniform Circular MotionCentripetal forces and centripetal accelerationProblem solving strategies for circular motionPeriod, frequency, and angular veloctiyBanked curve problemsThere are over 60 fully solved problems ranging in difficulty. I've mixed in many conceptual problems as well as algebraic problems to help you practice applying Newton's laws to solve problems. If at any point you don't understand something in my videos please feel free to reach out. I'm always willing to help someone learn. Physics Ninja always has your back!If have a specific problem not covered in this class simply email it to me and i'll add a video showing how to solve the problem.Happy LearningDr. E, Physics Ninja and Expert Physics and Math Teacher.
