Potential Energy- the energy in an object due to its position relative to others, energy stored within itself, or height.
Potential Energy of A Spring- this is the energy stored due to the deformation of an object. In our case a rubber band beingstretched between two pegs Kinetic Energy- energy due to motion. The equation for Kinetic Energy is KE=1/2 x mass x velocity squared. This was the force making the car move. Spring Constant- a measure of how easily a spring is compresses and expanded, or in our case the strength of the rubber band. To find this we used Spring Constant=Force/Distance Thermal Energy- potential energy converted into heat energy. In our car this was friction of the wheels with the ground and the axles, as well as the friction of the rails on each other. Total Energy- the total amount of kinetic, potential, and thermal energy in a moving object, the net energy acting on the object |
Reflection-
Out of my projects so far, I think my group worked the best this time around, I think that was from what I learned from past groups, and the competence of my group this time. Due to the overall smoothness of this project, there weren't a lot of mistakes I learned from. One thing I did learn is that sometimes it's best not to make your whole group focus on what you're doing, but to divvy up the jobs. Some were working on the car, while I worked on the presentation, I think this is the only reason we did it in time. One thing I think we could have done better is consider all solutions we came up with. So far I have not done that on every project, and it seems to be affecting my overall performance. I will make it a goal to improve on that. |
