Hello Everyone! I hope all is well and you enjoy the lesson. I've been absent, but will be around again soon!

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
