Speed, Velocity, Distance, Displacement and
Acceleration
2
Project Objectives

• Calculate the average speed of an object using
  the change of position and elapsed time.
• Create line graphs using measured values of
  position and elapsed time.
• Describe and analyze the motion that a
  position-time graph represents, given the graph.

3
Project Objectives

• The motion of an object can be described by its
  position and velocity as functions of time and by
  its average speed and average acceleration during
  intervals of time.
• Distinguish between the variables of distance,
  displacement, speed, velocity, and acceleration.
  Use the change of speed and elapsed time to
  calculate the average acceleration for linear
  motion. Describe and analyze the motion that a
  velocity-time graph represents, given the graph.

Focus

• Imagine that you and your friend are planning
  your spring break road trip. If you had millions
  of dollars and no responsibilities where would
  you go? The project below is designed for such a
  scenario. It is also designed to open your eyes
  to all the physics involved with traveling. You
  will be asked to pick a dream and discuss the
  different physics involved in your travels.

Slide 1

• Using Google Maps, map out a route from Lowell
  High School (address at lowellschools.com) to
  your dream travel destination.
• Take a screen shot showing the entire route and
  include it in this slide.
• On the map, insert a text box that explains
• Your total distance
• Your total travel time

Slide 2

• Copy your map onto this slide. Accurately Place
  your displacement vector on your map.
• Insert a text box and explain
• how your total distance traveled be different
  than your total displacement. Which will be
  greater?
• Insert another text box and explain how the
  spherical shape of the earth would have an effect
  on your displacement vector.

Slide 4

• Research 2 other destinations you want to stop at
  on the way to your final destination. If you have
  choose a nearby destination these could include
  stops for gas or food.
• Insert these destinations into Google maps and
  re-enter your route information into Google.
• Take a screen shot and place your map with your
  new updated route on this slide.

Slide 5

• Using Geogebra, construct a distance-time graph
  including a point at each stop. Keep in mind your
  slope should reflect your average speed. Also
  assume you are traveling non-stop back home.
• After constructing the graph you need to label
  each segment (you should have 7 segments) with
• the slope
• the distance and time elapsed during travel.
• the time elapsed during each stop.

Slide 6

• Paste your map from slide 4. On your map, Place
  and label a velocity vector at each stop showing
  your direction (N, S, E, W, NE, SE, SW, NW) and
  average speed away from the stopping point (you
  should have 4 vectors.

Slide 7

• From a stoplight, assume that it takes your
  vehicle 10 seconds to reach your average speed.
  What is your acceleration rate in ?
• After driving at your average speed for one
  minute, the light in front of you turns red and
  it takes your vehicle 8 seconds to come to a
  complete stop. What is your acceleration rate in
  ?
• Answer the above two questions, showing your work
  in equation editor. And include your answer on
  this slide.

Slide 8

• Using Geogebra, construct a Speed-time graph
  representing the scenarios from slide 7. Place
  a point at each place your acceleration changes
  (i.e. goes from positive to zero ect.) Keep in
  mind your slope should reflect your acceleration
  and lines should reflect your speed.
• After constructing the graph you need to label
  each segment (you should have 3 segments) with
• Positive, negative or zero acceleration
• Slope
