Published on Aug 28, 2016 This physics tutorial focuses on forces such as static and kinetic frictional forces, tension force, normal force, forces on incline planes and pulley systems. This video is useful for students taking high school and college level physics. This basic review / introduction tutorial contains plenty of notes, examples, equations / formulas and practice problems for you to master the concepts to prepare well for your next upcoming quiz / exam.Here is a list of topics:1. Newton's First Law of Motion - An object at rest will remain at rest and an object in motion will remain in motion unless acted on by a net force - Law of Inertia.2. Newton's Second Law of Motion - Force equals mass times acceleration.3. Unit Conversion - Newton, Kilogram or Kg, m/s2, and lbs.4. Mass vs Weight on Earth and Moon - Force of Gravity5. Newton's 3rd Law of Motion - For every action force, there is an equal an opposite reaction force6. Newton's third law of Motion Examples - Rocket Propulsion, Book on a Table, Force of Gravity Between Earth and Moon, Throwing a Package off a Boat, Pushing off an ice skater7. Acceleration Due to Gravity of Earth and Moon8. Contact Force / Normal Force - Perpendicular to Surface9. Normal Force and Tension Practice Problems10. How To Calculate the Tension Force on a rope connecting to hanging box with upward and downward acceleration plus constant speed / velocity.11. Net Force - Sum of Forces in X and Y direction - Sigma Notation12. Resultant Force - Adding Force Vectors that are parallel and perpendicular13. Physics and Trigonometry - SOHCAHTOA - Pythagorean Theorem and Right Triangle Trig.14. Sine, Cosine, and Tangent Functions15. Horizontal and Vertical Force Components - Fx and Fy16.
