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

1 2.571
2 2.587
3 2.570
4 2.310
Average of trial 1,2 and 3
2.576
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

HANDS DON'T TELL TEMPERATURE
They sense heat.
Heat- The transfer of energy between objects that are different temperatures.

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!!

My family is Nobel gas!! The other families I know are the Non metal family,
