  • Homework Assignments
    • Due Sunday, Written homework, Math Exam, & Ch. 3 Online homework
key concepts physics 1d motion
Key Concepts: Physics 1D Motion
  • Displacement, Velocity, & Acceleration
    • Know the definitions of these terms
    • Know how they are related
  • Motion with Constant Acceleration
    • Solve for constant accel. get Kinematic Eqs.
    • Use the Kinematic Eqs. to solve problems
      • Free Fall
      • Race Car
what is constant acceleration
What is constant acceleration?
  • Examples of a ≠ constant?
    • Bee flying
    • Dust Particle in the wind
  • Acceleration = constant (0 or some #)
  • Velocity can be approximated as linear
  • How many of these things have a=const?
    • Trains
    • People
    • Planes
    • Cheetahs
    • Automobiles
free fall using the equations
Free Fall – Using the Equations
  • Constant acceleration is due to gravity
  • Drop a ball from 3 m, how long does it take to hit the ground?
free fall what does it imply
Free Fall – What does it imply?
  • Demo: Falling Balls
  • Demo: Feather vs. Penny

free fall what does it imply1
Free Fall – What does it imply?
  • Acceleration of any size or mass object should be the same
    • Penny should fall at the same rate as feather
    • This isn’t true due to air resistance
    • In vacuum it is true!

Lingenfelter Corvette
  • Can it really do 0 to 60 mph in 1.97 s?
  • Let’s calculate some #’s to see if it is reasonable

is it true
Is it true?
  • Stock Car – 220,000 miles/hr2
  • Lingenfelter Corvette – 110,000 miles/hr2
  • C6 Corvette – 51,000 miles/hr2
  • Yes, let’s look at some data from youtube…
summary
Summary
  • Most physical objects experience constant acceleration
  • Use Kinematic equations of Motion to solve for problems with constant acceleration
  • Examples: Free Fall and Race Car
