Conservation of Energy
Use a motion sensor to detect how energy is transformed in a cart and track system and to observe that the total energy of the system is conserved.
Students observe the behavior of a cart and track system to see how energy is transformed. By comparing the extremes of the system, the students see that the total energy of the system is conserved. Students:
- Determine the points of maximum gravitational potential energy and kinetic energy.
- Calculate values for gravitational potential energy and kinetic energy.
- Compare the total energy values to other points in the system to prove that energy is conserved.
In this investigation, students gain experience with the following tools and techniques:
- Measuring the motion of a cart and track system using a motion sensor.
- Interpreting a graph of Position versus Time and Velocity versus Time to determine critical points in the motion of a cart.
- Employing basic trigonometric relationships to calculate gravitational potential energy.
