Percentage of total beginning GPE converted to thermal/kinetic energy

Click For Summary
SUMMARY

The discussion focuses on calculating the percentage of gravitational potential energy (GPE) converted to kinetic energy (KE) and thermal energy in a roller coaster project. Key formulas for these calculations are provided, emphasizing the relationship between GPE, KE, and thermal energy. The discussion highlights that thermal energy is essentially heat generated due to friction, which results in a loss of mechanical energy. For precise calculations, users are directed to HyperPhysics for relevant formulas.

PREREQUISITES
  • Understanding of gravitational potential energy (GPE)
  • Knowledge of kinetic energy (KE) calculations
  • Familiarity with the concept of thermal energy and heat
  • Basic principles of mechanical energy conservation
NEXT STEPS
  • Review the formulas for calculating gravitational potential energy and kinetic energy
  • Explore the concept of energy loss due to friction in mechanical systems
  • Learn about the conservation of mechanical energy in roller coaster dynamics
  • Investigate the role of thermal energy in energy transformations
USEFUL FOR

Students in physics, engineers involved in roller coaster design, and anyone interested in energy conversion principles in mechanical systems.

These are calculations for a roller coaster project where we had to find the height, GPE, velocity, KE, and total ME.
Question 1: what percentage of the total beginning GPE was converted to final kinetic energy?

Question 2: What percentage of the total beginning GPE was converted to thermal energy? (and what is thermal energy?)

I just need formulas, thanks.

Welcome to PF, Linkme.
You can find all the formulas here: http://hyperphysics.phy-astr.gsu.edu/hbase/enecon.html

Thermal energy is heat. Perhaps you have some friction in your coaster so you end up with less mechanical energy than you started with. The loss is in the form of heat.
