Speed and Acceleration

In this search we learned stuff on the web about speed and acceleration.
1) The difference between instantaneous and average speed are: Average speed is the distance traveled in a given period of time. Instantaneous speed is a speed at a certain instant. You are reading your instantaneous speed when looking at your speedometer.
2) Constant speed is when you go the same speed for a period of time. It would travel 300m.
3) Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. Average Acceleration = Vf-Vi/time. Three units for acceleration are: m/s/s, mi/hr/s, and km/hr/s. It would be going 28 m/s/s.
Part II
1) The slope of a position vs. time graph is the velocity. The velocity increases.
2) -3m/s and the second one is 4m/s
3) The slope of a velocity time graph is acceleration. The line for acceleration will be going on a upward, rightward slope. Deceleration would be the opposite.
Part III
1) It means that the objects do not encounter air resistance. It accelerates downwards at a rate of 9.8 m/s/s
2) The velocity is increasing as it falls downward. Its acceleration as its falling is 3.75 m/s/s.

Last Mousetrap Vehicle Post

Things that were successful: 

• I think that the things that were successful were that our vehicle kept on getting better every time that it went. Each time we tested it, it gained a meter.
• Also that we gained a lot of experience in building things by doing this.

Future Recommendations:

• Not have the mousetrap break of of the vehicle right before the race.
• It was not very consistent so we could have adjusted something so it would have went consistently instead of going another meter each time.
• We could have made the wheels tighter so there wouldn't have been such a big wobble in it.
• I think that we should have used a lighter chassis instead of a heavy piece of wood.
• Maybe using different wheel could have helped it go farther and may be even a little faster to.

Race Day Post

 Our vehicle got better and better each trial. It went just over 2 meters the first time. Just over 3 meters the second time, and on the last trial it went a little over 4 meters. For this i come to the conclusion of that our vehicle was not very consistent.

This is our third and final trial. We went just a tad bit over 4 meters on our final run. This was our most successful one.

If i were to modify our car i would probably try and get rid of the wobble in the wheels and hopefully that would get it to go farther.

I would probably use a lighter chasis on the vehicle and maybe some different tires that would help us go further.

Better wheels would help it perform better.
