Key Terms and Concepts That I Need to Know and Their Definitions:
- Potential Energy:This is energy that is stored at the top of roller coasters and it stores all the enrgy that the Roller Coaster needs for the whole roller coaster but especially for the big drop.
- Kinetic Energy:This is also known as motion energy and the roller coaster uses a lot of motion energy so that it can move.
- Conservation of Energy:This is energy that can turn into differnt forms so for example a roller coaster can go from potential to motion energy.
- Gravity:This is force that makes something fall in a forcefull way so for example when a roller coaster is going down on a big and steep hill besides for the motion energy there is also gravitational energy happening at the same time.
- Velocity:This is bassicly speed that is going in a certain or specific direction.
- Friction:This is when two things rub against each other and cause a form of energy or something else to happen or help something move forward.
- Slope (Rise/Run):This is almost like an incline plane becase its like a hill where there is the top which is very tall and high and then as the hill goes down it gets littlier and lower.
| Materials I Used: |
| I used duct tape,foam for the actual roller coater,a wall to hold up the first part of the roller coaster and to give it potential energy,and diffrent colored marbles to use as a roller coaster “car”. |
Here Is A Picture and Video of My Project and This is Also The Roller Coaster That Worked:
Here is a Summary of My Project:
| What starting height was needed for the marble to make it through the loop most of the time?
We needed the top of the roller coaster to be about 2 and a half feet so that when it went up and down the loops it didn’t touch the floor and it got a head start for lots of motion and gravatational energy for then next loop. |
| What can you determine about the relationship between potential energy and kinetic energy?
Motion energy can only happen if there is potential energy(Stored energy) so bassicly what happens is that while the roller coaster is at the “peak” right before the BIG DROP thats where the potential enrgy is and then especially in the middle of the big drop for the roller coaster is where the most motion energy is(usually).So they are related because they work togther to make the roller coaster be able to go and also because of what I said above. |
Sadie, nice job! Please revise your blog post to include definitions of the vocabulary words, as required by the project rubric.
Thanks so much! I just put in the definitions.
