=** Car lab!!! **= __** Potential **__ we have found that there is nothing wrong with our car we have, it stay on the track and does down the track in a straight line. we will be finding gravitational potential energy by finding the weight of the car and height of track. Height of starting line is 95.6 cm finish line is 90.2 cm The height of the ramp is 5.4 cm-0.054 meters Mass of car 33.7 g- 0.00337 kilograms Weight of car is mass x 9.8 = .333 newtons weight x height= 0.02 joules =**Trial / Time**= length (m) 1.0 mass(kg) 0.0337 Time(s) 2.576 Final velocity(m/s) .776 =**Summary**= During an energy conversion,come energy i always transformed into heat.We found out there is more potential energy at the top then kinetic and more kinetic energy at the bottom then potential energy

//__**Materials**__// They sense heat. Heat- The transfer of energy between objects that are different temperatures.
 * Metal-Coldest
 * Cardboard- Warm
 * Plastic- Warm
 * Foam- Warm
 * Tile-Cold
 * Wood- Warm
 * //__Temperature__//**
 * Metal- 21.6 degree c
 * Cardboard- 206 degree c

 * HANDS DON'T TELL TEMPERATURE**

12-16-13 Temperature- A measure of the average kinetic energy of the particles in and object. (Thermal energy is the total kinetic energy of the particles but temperature is the average kinetic energy of the particles) Thermal Equilibrium- When there is no change in either object's thermal energy.

Test subject- Which tube of water is the warmest? They have one hand in ice water and the other in warm water, then after a few minutes they take their hands out and then put them into another bucket that is room temperature. ENERGY ALWAYS GOES FROM A HIGH TEMPERATURE TO A LOW TEMPERATURE!!
 * Test Subject || Which tube water is the warmest?? ||
 * Zac || Tub B ||
 * Eddie || Tub B Tub A is 21.6 degrees ||
 * Luke || Tub B Tube B is 20.8 degrees ||
