∑
Formula
Principle: To demonstrate the conservation of mechanical energy and the interconversion of kinetic and potential energy using a roller-coaster track simulation.
🎯
Aim
To demonstrate the conservation of mechanical energy and the interconversion of kinetic and potential energy using a roller-coaster track simulation.
🧰
Apparatus
- Roller-coaster track (virtual)
- Ball of variable mass
- Height-adjustable ramp
- Energy meter display
🧪
Procedure
- Set the initial height and mass of the ball.
- Release the ball from rest and observe it gaining speed as it descends (PE → KE).
- Observe the ball slowing as it climbs (KE → PE).
- Monitor the energy bars and graph to verify total energy stays constant.
- Enable friction and observe energy loss as heat.
- Try different track shapes by dragging control points.
