- Potential energy (stored energy)
- Kinetic energy (energy of motion)
- Conservation of energy (basic law of physics)
- Gravity (when you jump, you come back down, and that’s gravity)
- Velocity (how fast something goes in a certain direction)
- Friction (when something rubs on another thing)
- Slope (rise/run) (something that tells how steep and what direction a line is going in)
| Materials I used: |
| I used tape and the two six foot pieces of foam tube |
Visuals of my project:
I don’t have the pictures right now, I will put them up when I can.
Summary of my project:
My roller coaster didn’t work, so we don’t have anything to measure. The reason I think it didn’t work is because where the two tubes were taped together, they kind of got apart, so the marble would get stuck in the middle of them/
| What starting height was needed for the marble to make it through the loop most of the time? |
| I didn’t measure it yet. |
| What can you determine about the relationship between potential energy and kinetic energy? |
| The kinetic energy starts at the top of the loop when the marble starts moving and the potential energy starts at the top of the loop. |
