member in two scenarios (going up and down the stairs of the second floor and the third floor of the Main Building) wherein weight was also considered and following this‚ the power output of each member was also computed. Using the Logger Pro‚ the kinetic and potential energies of a ball in free fall were graphed and compared. At the end of the experiment‚ it was said that member #2 was the most “powerful” among the group since she had the highest power output both in going up and going down the stairs

Balloon powered car 1 How does the balloon car demonstrate that energy is transformed from potential energy to kinetic energy? Explain When the balloon has air inside it‚ the car and the balloon have potential energy stored inside it. When the air is released the car moves forward and has kinetic energy. 2 Where is most of the energy ’lost’ in this car? There is a number of different possible reasons that energy could have been lost in our car: some of the air in the balloon may have escaped through
Premium Wheel Energy Potential energy
My car utilizes the energy stored within a stretched rubber band‚ and converts it into rotational kinetic energy‚ which moves the wheels forward. 2 non-motile rods were placed on the front of the chassis to maintain tension in the rubber bands‚ and allow the rubber band to retract as it leaves the axle‚ preventing it from limiting axle motion. The CD wheels on the rear of the vehicle allow a larger displacement per axle rotation‚ meaning the car will be able to travel a farther distance. Vinyl tape
