Class on Tuesday December 1

The first thing that we did in class was take a reassessment on chapter 3. Then, we turned that in and continued our discussion of how different things hurt us and why. We concluded that objects can hurt us for many different reasons, including mass, velocity, displacement, and heat. We also guessed that how objects hurt us is related to energy. Then we derived an equation with displacement and acceleration in terms of final velocity and initial velocity. Then we took a break, and when we got back, Mr. Burk gave us propsicles. After the break we started on a lab. We set up a cart and a spring on a ramp, and launched the cart on the ramp with different inclines. This is what the set up looked like.

We measured many different aspects of the cart's motion as we changed theta, the angle of elevation of the ramp. Specifically, we measured the cart's maximum velocity and we measured the hight that the car traveled. We found that the height remains the same regardless of the angle. Finally we started working on the energy work packet. We discussed the types of energy that we know so far: kinetic and potential, but we can't call it potential because we don't understand what that means. That's all we did. Homework is test corrections, and the next blogger is Dylan.
