Chapter 2 Notes Representing Motion Chapter Objectives Draw and interpret motion and particle

diagrams. Define displacement and time interval and solve for them using given equations. Draw and interpret position vs. time graphs illustrating motion.

Differentiate between vectors and scalars. Use average velocity equation to solve motion problems. Differentiate between average velocity and instantaneous velocity.

What is motion? How do you know something is moving? What evidence do you need to be

convinced that something is moving? Motion Diagrams What can you

determine about the motion of the bird? The runner? The car?

Particle Diagram Coordinate Systems Indicate direction

Quantities Vectors quantities that have magnitude

and direction Represented with arrows Scalars

quantities that have no direction Adding Vectors Line up vector arrows from tip to tail

Add magnitudes to find resultant vector Subtracting Vectors Treat subtraction as addition of

vectors with a negative sign Displacement d = df - di

Distance vs. Displacement A jogger travels 2 km, stops to rest, then jogs back to his starting place. What is the distance the jogger traveled?

What is his displacement? Time Intervals t

Position-Time Graphs Position vs. Time Graphs What does the slope of a positiontime graph tell us?

Motion Diagram Position-time Graph of Runners

Speed vs. Velocity Instantaneous Velocity Speed and direction at a particular instant

Speedometer How can we determine this on a position-time graph?
