If you ever feel bored in class and want to be challenged, just let me know.

I will keep a list of advanced topics here that we can examine at outside of class.

Kinematic Videos

Here are some videos from a physics class.

Note: They use 10 m/s^2 (sometimes 9.8 m/s^2) for the acceleration of gravity. In our class we are using 32 ft/s^2

Here is a link to a presentation on vectors. It is really good.

Quiz Friday

Quiz this Friday. Topics that are fair game include:

  • Solving quadratic equations with either exact answers or decimal equivalent
  • Solving for distance traveled for a moving object
  • Solving for the final velocity of a moving object
  • Solving for the time it takes a moving object to move a certain distance

Are you ready? Questions?

Look Out Below

Its been a long time....

Today, we reviewed the answers to Look Out Below

1. 1 sec = 50 ft/sec; 2 secs = 70 ft/sec

2. Avg speed is 50 ft/sec (How did we get this?)

3. Travel 100 feet in 2 secs (Can you use the area model to get this?)

4. 3.2 secs to fall 200 feet (Can you use the area model to get this? -OR- Can you use the equation below to get this answer?)

5. h(t) = 200 - 10t^2 - 30t. This is derived from the physics formula that some students remember: displacement = 0.5*a*t^2 + vi*t

The top of this page has more information on the formulas we are interested in.

Here is a site that can help with the physics concepts. We also proved some of them in the assignment "FreeFall".
