Hybrid Car
Problem &solution:
For our hybrid car project we were faced with a challenge of designing a car that could not run on gas or electricity. We had about a week and a half to come up with a concept, design and build our car, and to present our idea.We came up with the idea to power our car using a rat trap.
The project was harder than we thought to figure out. We decided that we want to have the part of the rat trap that snaps to be attached by a piece of string to the axle. To make the car go you will need to wind up the string and pull back the mouse trp. When you release it the car will start to go.
Time~ Our first concept was time. The variable for time is (t) and the definition of time is the "progress of events". A unit used for time can be seconds(s). We used time throughout our project to solve different equations. Time can be used to calculate things like velocity, speed, and acceleration. We used all of these a lot in our project calculations. Time is very frequently used in calculations for ramps.
Distance~ The second concept we learned about was distance. The variable for distance is (d) and the definition is the "amount of space between two points". Distance has many units, but one of the most commonly used units is meters (m). Distance was another very important component to our calculations. Distance can be used in equations that have to do with velocity, speed, and work.
Change~ Change is a very important concept because it is used in a lot of equations. The variable for changed looks like a triangle. It is the Greek symbol delta, which means the change in difference. It is used in almost all of our physics concepts.
Velocity~ The fourth concept that we learned was velocity (v). The definition of velocity is the "rate of distance covered in a direction". The equation for velocity is the change of distance over the change in time. The unit that is used in this is meters per second.
Speed~ Next, is speed (S). The variable for speed is (S), not to be confused with (s) which is seconds. the definition of speed is the "rate of distance covered". This is used in some of our equations, but speed is a similar concept to acceleration. The unit used for speed is meters per second.
Acceleration~ Acceleration is a very important concept for physics. The variable is (a) and the unit is meters per second squared. The definition for acceleration is the rate of change of velocity/ or speeding or slowing. The equation for acceleration is the change in velocity over the change in time.
Sum~ This concept it is a very important one, it is a sum. The variable is a the Greek symbol that looks like a side ways M. This symbol is called a sigma. The definition is to "add all of following or total".
Mass~ Mass is a concept that has to do with weight. The variable for mass is (m). The definition for mass is the "amount of matter or number of atoms". The unit for mass is a kilogram or (kg). Mass is used to calculate mainly force.
Force~ The next concept is force, force is very important. he variable for force is (F), the definition is a "push or pull on a n object". The equation for force is force equals mass times acceleration. The unit for force is Newton's.
Work~ This concept is work, work is the "amount of energy put into something". The variable for work is (W). The equation for work is, work equals force times distance. The unit used in work is joules.
Kinetic Energy~ The second to last concept is kinetic energy. The variable for kinetic energy is (KE). The definition is the "energy due to motion". The equation is kinetic energy equals one half mass times velocity squared. The unit for kinetic energy is joules.
Mechanical Advantage~ The last concept is mechanical advantage, the variable is (MA). There is two different types of mechanical advantage real and ideal. The definition of mechanical advantage is " how much easier a tool makes something and how much further".

PEspring~
PEspring~ stands for the potential energy of the spring. It ties in with our project because had multiple springs to make it work.
I feel like I accomplished work efficiency really well. A lot of the things wanted to get done I ended up doing it. I was very focused on what I wanted to get done. I also felt that I did a great job at leadership. I tried to keep everyone in line and I helped move the process along. When our group would get off task I would steer them back into the right direction.
I still need to improve on being more open to other ideas. I felt that I just need to listen to other people more. I also feel I need to work on my attitude. I feel like I could be a lot nicer and more people could share their ideas. They both tie together in a way.
