  9. Kinematics: Position EQ: How can the position of an object be measured and quantified? Start: Turn and tell partner where your house is, discuss where Pittsburgh is?

  10. How can the motion of an object be described in a measurable and quantitative way? Units of 1-D Kinematic Motion • Reference Frames and Displacement • Average Velocity • Instantaneous Velocity • Acceleration • Motion at Constant Acceleration • Solving Problems • Falling Objects • Graphical Analysis of Linear Motion

  11. How can the position of an object be measured and quantified? Reference Frames and Displacement Any measurement of position, distance, or speed must be made with respect to a reference frame. For example, if you are sitting on a train and someone walks down the aisle, their speed with respect to the train is a few miles per hour, at most. Their speed with respect to the ground is much higher.

  12. How can the position of an object be measured and quantified? Reference Frames and Displacement We make a distinction between distance and displacement. Displacement (blue line) is how far the object is from its starting point, regardless of how it got there. Distance traveled (dashed line) is measured along the actual path.

  13. How can the position of an object be measured and quantified? Reference Frames and Displacement The displacement is written: Left: Displacement is positive. Right: Displacement is negative.

  14. How can the position of an object be measured and quantified? Does a odometer measure distance traveled or displacement? • Insert Picture of Jeff (aka. Cameron) here. • Ferris Bueller’s Day off Ferrari (with 301 mi) through window.

  21. Kinematics: Velocity EQ: How can the velocity of an object be measured and quantified? Start: Compare themotion of a turtleand a train. Howdo you know it ismoving fast or slow?

  22. How can the velocity of an object be measured and quantified? The Turtle vs. The Train Can the turtle make it to the water before a train passes by (or hits it)?

  23. How can the velocity of an object be measured and quantified? Average Velocity Speed: how far an object travels in a given time interval (2-1) Velocity includes directional information:

  24. How can the velocity of an object be measured and quantified? Instantaneous Velocity The instantaneous velocity is the average velocity, in the limit as the time interval becomes infinitesimally short. (2-3) These graphs show (a) constant velocity and (b) varying velocity.

  25. Pasco Position-Match Lab(if we can get it to work:) Work in groups of no more than 4 people. Return all supplies to the counter/cart. How can the velocity of an object be measured and quantified?

  26. WebAssign/Lab Time Work on WebAssign Problems 2.7 - 2.12 or Position-Match Lab Final Copy Criteria State the problem (Ex. Find displacement) Draw a picture/diagram Provide a list or table of all given data (Ex. t = 2 s) Solve the problem symbolically (Ex. v=x/t  x = vt) Plug in numbers and units to obtain answer. (Ex. x = (5 m/s)(2 s)= 10 m) Notes about WebAssign: Positive vs. negative answers (Try a negative sign) Look at the final unit (hours or minutes or seconds) How can the velocity of an object be measured and quantified?

  32. How can the acceleration of an object be measured and quantified? Voxel Victor • What is its acceleration? 2200 hp 0-60 in 1s!!!

  33. How can the acceleration of an object be measured and quantified? Acceleration Acceleration is the rate of change of velocity.

  34. How can the acceleration of an object be measured and quantified? Acceleration Acceleration is a vector (magnitude and direction), although in one-dimensional motion we only need the sign. The previous image shows positive acceleration; here is negative acceleration: How long will it take the car to stop? 7.5 s How fast will it be going after 10 s? 0 m/s; unless the driver put it in reverse.

  35. How can the acceleration of an object be measured and quantified? Acceleration There is a difference between negative acceleration and deceleration: Negative acceleration is acceleration in the negative direction as defined by the coordinate system. Deceleration occurs when the acceleration is opposite in direction to the velocity.

  37. How can the acceleration of an object be measured and quantified? Frame of Reference UP (+) UP (+) Speed Up UP (+) DOWN (-) Slow Down DOWN (-) DOWN (-) Speed Up DOWN (-) UP (+) Slow Down

  38. How can the acceleration of an object be measured and quantified? Acceleration Is the car undergoing positive or negative acceleration? positive acceleration (velocity is in the negative direction!) Is the car accelerating or decelerating? decelerating If the following scenario takes place in 1 second, what is the car’s acceleration?

  39. How can the acceleration of an object be measured and quantified? Acceleration Using the previous reference frame is the car undergoing positive or negative acceleration? Negative acceleration Is the car accelerating or decelerating? Accelerating What is the car’s velocity after 1 second if it is accelerating at -10m/s2?

  40. How can the acceleration of an object be measured and quantified? Acceleration The instantaneous acceleration is the average acceleration, in the limit as the time interval becomes infinitesimally short. (2-5)

  41. How can the acceleration of an object be measured and quantified? Calculus Applications of Motion For those who have or have had calculus: Velocity is the time derivative of position: Acceleration is the time derivative of velocity: The “jerk” function is the time derivative of acceleration: The change in jerk (known as the “marriage” or the “nagging spouse” function) is the time derivative of jerk: Finally, the change in the change in jerk (*only known as the “death” function) is the second time derivative of jerk: *Please note: Death is the only thing that can really change a jerk.
