  1. AP Physics C Mechanics Review – SEMESTER 1

  2. Kinematics • Position vs. displacement • Speed vs. Velocity • Acceleration • Kinematic Equations for constant acceleration • Vectors and Vector Addition • Projectile Motion – x,y motion are independent • Uniform Circular Motion

  3. Kinematics –Motion in One and Two Dimensions Key Ideas and Vocabulary • Motion in the x is independent from motion in the y • Displacement, velocity, acceleration • Graphical Analysis of Motion – • x vs. t - Slope is velocity • v vs. t - Slope is acceleration - Area is displacement • a vs. t – Can be used to find the change in velocity • Centripetal Acceleration is always towards the center of the circle

  4. Kinematics –Motion in One and Two Dimensions Constant Acceleration Motion Equations Centripetal Acceleration 

  5. TYPES OF PROBLEMS • Applying the equations of motion in single direction • Projectile motion. • Projectile combined with circular or linear motion • Relative motion – working with subscripts. Any other types ? List here

  6. Newton’s Laws of Motion • Newton’s Three Laws of Motion • Inertia • Fnet = ma • Equal and opposite forces • Force • Weight vs. Mass • Free Body Diagrams • Tension, Weight, Normal Force • Friction – Static and Kinetic, Air Resistance • Centripetal Forces and Circular Motion • Drag forces and terminal speed

  7. Newton’s Laws of MotionSecond Law Problems • Newton’s Second Law – • Draw free body diagram identifying forces on a single object • Break forces into components • Apply 2nd Law and solve x & y components simultaneously • Inclined Plane – • Rotate axes so that acceleration is in the same direction as the x-axis

  8. Types of Problems • Inclined plane • Atwood’s machine • Elevator • Atwood’s in elevator • Man pulling himself up using a pulley • Pulley on a table • Pulley on inclined plane • Third Law and stack of books problems Any other types ? List here

  9. Newton’s Laws of MotionCircular Motion Problems • Draw free body diagram identifying forces on a single object • Break forces into components • Apply 2nd Law and solve x & y components simultaneously • Remember that the acceleration is centripetal and that it is caused by some force

  10. Types of Problems • Uniform circular motion • Horizontal circle • Vertical Circle • Centripetal acceleration and force. • Linear velocity • Relationship between Angular velocity, Time Period and Frequency • Banked curves / Merry go round.. What supports the centripetal acceleration • Any other types ? List here

  11. Newton’s Laws of MotionAir Resistance – Drag Force • Identify forces and draw free body diagrams • May involve a differential equation • Example: • Separate variables and solve. Should end up with something that decreases exponentially • Terminal Velocity – Drag force and gravity are equal in magnitude – Acceleration is equal to zero

  12. Types of Problems • Static, Kinetic Friction – How do they effectiveness of applied force • Drag force • Terminal velocity = constant velocity • Hooke’s law. WD by spring as area under the curve of F(x) vs x graph Any other types ? List here

  13. Work, Energy, Power • Kinetic Energy • Work – by constant force and variable force • Spring Force • Power • Potential Energy – gravitational, elastic • Mechanical Energy • Conservation of Energy • Work Energy Theorem

  14. Work, Energy and PowerKey Equations Work Work by a Constant Force Power Kinetic Energy Work-Energy Theorem

  15. Types of Problems • Work done by various forces and then finding net force. • When is work + and when is it – • When the angle between Force and displacement is not 0 • Net WD = change in KE ( final – initial) • Combination of gravity, spring, friction and inclined plane • Any other types ? List here

  16. Work, Energy and PowerKey Equations

  17. Types of Problems • PE (U) and KE (k) • Conservative and non conservative forces • Law of Conservation of Energy • Ki + Ui = Kf +Uf + Workdone of NC forces like friction • Usage of this in Spring, in Gravitational field, pendulum • Application of concepts of circular motion to roller coaster and energy transformation at various levels Any other types ? List here

  18. Potential Energy Curves • Slope of U curve is –F • Total energy will be given, the difference between total energy and potential energy will be kinetic energy

  19. Types of Problems • Solving of min and max of a PE function • Finding stable/ unstable equilibriums. • Tracing Force and KE curves from PE curves • Identifying turning points and forbidden ranges • Finding maximum allowable energy level using K and U Any other types ? List here
