Position A (top of the first hill): Maximum potential energy, minimum kinetic energy, and little to no thermal energy.
Position B (going down): Potential energy decreases as the cart moves down, and kinetic energy increases.
Position C (bottom of the valley): Maximum kinetic energy, minimum potential energy, and possibly some thermal energy due to friction.
Position D (top of the second hill): Potential energy increases again, kinetic energy decreases, and thermal energy may still be present, This image illustrates the energy transformation of a cart moving on a hilly track. At Position A, the cart has maximum potential energy and minimal kinetic energy. As the cart descends to Position B, potential energy decreases while kinetic energy increases. At Position C, at the bottom of the valley, the cart reaches maximum kinetic energy and minimal potential energy. Finally, Position D shows the cart climbing the second hill, where potential energy rises again, and kinetic energy decreases. These positions represent the fundamental principles of energy conservation and transformation
