Hybrid Car Battery Designs
In this project we had to design a car to present to Hyundai. This car had to travel 5m and the car had to hold 250kg or 100 pennies. Our car was longer and more efficient than our peers because we used springs to power our car so it is very efficient.
Our car works because a string is attached to both springs and the other end of the string gets attached to an axle. The string rolls around the axle to a certain distance.
Our car is perfect because it will eliminate the decreasing amount of gas in the world. Also it will be a lot cheaper and can be sold for a big profit which might help our economy out a lot.
Concepts of Car
Potential energy- is the energy of an object or a system due to the position of the body or the arrangement of the particles of a system. Potential energies formula is Pe=mass x gravity x height. At the start of the run it is at its highest amount but as it moves on the car loses all its PE.
Kinetic energy- is when the objects energy which it possesses due to its motion. The formula is Ke= 1/2 x mass x velocity squared.
The kinetic energy is different due to air resistance or the friction of the springs. The KE at the beginning is 0 J but picks up to joules but then since the car stop the kinetic energy is gone.
Thermal energy- is the total energy of PE and KE. There is no thermal energy at the start but as the PE and KE lose all there energy due to heat the thermal energy is significantly larger than at the beginning.
Acceleration- is the increase rate of speed of an object. The first couple of meters our car accelerates but then it decelerates so its acceleration goes into the negatives.
Velocity- is speed with direction. The formula is Velocity=Distance/Time. Our car has a great velocity at the beginning but slowed down in proportion to the distance traveled.
Take Aways From Project
I have learned how to create a good presentation on a computer that involves graphs. This will allow me to help my future groups with some computer concepts. Also i have learned to accept all kinds of different ideas from my group members. In the future this should help my groups fully consider ideas that might not sound good at first but could materialize into something more.
I could have been more professional on the day of the presentation. Since I didn't rehearse and dress appropriately I won't forget for next time. Next time I will try to divide the work equally between each group member. I feel as though some of the work was one sided.
Together we made this a successful project.
