Physics Kinematics and Forces Review (What to Know Plus Examples)

Physics Basics

  • Scientific Notation
    Non-zero numbers always count.
    Zeros before numbers never count.
    Zeros after a number count if there is a decimal point.
    When multiplying/dividing keep least number of significant numbers.
    When adding and subtracting keep the least precise decimal place.
  • Dimensional Analysis
    Know how to convert feet to meters, meters per second to miles per hour, etc.
  • The Scientific Method
    Introduction/Hypothesis
    Experiment/Procedures/Materials
    Data/Analysis
    Conclusion

Motion in 1-Dimension

  • (distance = rate * time)
  • (Average Velocity)

Accelerated Motion

  • (Average Acceleration)
  • (Used to find distance when there is acceleration)
  • (Used to find instantaneous velocity/speed at a certain time)
  • (Used with an average velocity and no time)

Forces in 1-Dimension

  • Newton’s First Law: An object will remain at rest or in constant motion unless acted on by an outside force.
  • Newton's Second Law: Force = Mass * Acceleration
  • Newton's Third Law: For every action, there is an equal and opposite reaction.
  • Free Body Diagrams and Equilibrium
  • Review the blocks on a pulley problem!

Forces in 2-Dimensions

  • Know how to add vectors in rectangular <x,y> and polar coordinates <r,θ>
  • This section is basically the same as 4, but with more concepts
  • Know how to break vectors up into components (the x and y directions)
  • Static Friction:
    If static friction is greater than the force that causes movement, no movement occurs.
  • Kinetic Friction:
    If the kinetic friction is greater than the force that causes movement, then the object will slow down.

Motion in 2-Dimensions

  • Same concepts as CH 3 with vectors
  • Always break velocity up into x and y components dependent on θ
  • Know velocity/acceleration in the x versus the y direction
