PHYSICS

COURSE EXPECTATIONS AND GOALS

We will study the classical areas of physics: mechanics; including kinematics; Newton‚Äôs laws of motion; work; energy; power; momentum; simple harmonic motion; heat; kinetic theory and the laws of thermodynamics; electricity and magnetism; waves and sound; and waves and optics. We will greatly reinforce your algebra skills; your vector skills; your trigonometric usage; and your ability to interpret graphs. Mostly; we will try to understand; a little better; this wonderful; amazing world of ours.

Coursework

Assignments (computer-graded and teacher-graded)

Quizzes/Tests (computer-graded and teacher-graded): One attempt is given with a 60 minute time limit.

Final Exam

When you complete all of the coursework and your instructor has reviewed it; you will be given permission to take the final exam.

Role of Homework

Physics is very much a participatory sport. Reading and problems will be assigned at the beginning of each chapter; and discussed in class. There will be laboratories based on the chapters in the book and lab write-ups will be submitted for grading. I strongly urge you to keep your problems in an orderly fashion in a notebook. This notebook facilitates study for tests and final exams.

The online textbook we use is called Holt Physics by Serway & Faughn.

Grading

Tests will be given at the end of each chapter; or at the end of two chapters. Tests will count for 70 percent of your grade; laboratory and homework 30 percent.

Learning objectives:

- Apply the properties of kinetic and potential energy

- Identify and describe the transfer of potential energy to kinetic energy

- Describe the effects of gravity

Initially; run the default simulation. Check the show grid box.

Using the height for the skater‚Äôs position from the grid; complete the table by using the equations for potential and kinetic energy. (25 pts)

Mass of skater ______________

**Students complete a table for the following at different positions on the ramp**

Skater‚Äôs

Energy (J)

Kinetic Energy (J)

Velocity

(m/s)

Include calculations for the skater when his position is in between the top and bottom of ramp.

You just hired to design a skate park for your community. Your park needs to be fun and exciting; yet safe. There should be at least 3 different features in your park (located on the menu bar >tracks). The challenge is to ensure your features are safe; and that your skaters will not fly off the ramps. (15 pts)

Have fun designing!!!

Sketch your new park:

1. On your sketch in number 1; label all the points of maximum kinetic energy in red; and all points of minimum kinetic energy in blue.

2. On your sketch in number 1; label all the points of maximum potential energy in green and minimum potential energy in orange.

3. How does the potential energy relate to the kinetic energy at these points you labeled?

4. Also on your sketch; label all points where kinetic energy is exactly equal to potential energy in pink.

Now let‚Äôs make some adjustments to your park:

5. Would this park be more or less safe on the moon? Why?

6. Would this park be more or less safe in space? Why?
