Question 58

The kinetic energy of the ball is converted to gravitational potential energy.

Just after the ball leaves the stick, it possesses kinetic energy due to its motion. As the ball ascends, this kinetic energy transforms into gravitational potential energy until it reaches its highest point.

A) The thermal energy of the ball is converted to elastic potential energy.

This option is incorrect because the scenario does not involve thermal energy or elastic potential energy. The process described focuses on the motion of the ball, not the thermal state of the ball or any elastic properties.

B) The kinetic energy of the ball is converted to gravitational potential energy.

This option is correct. The ball's initial kinetic energy, imparted by the stick, is converted into gravitational potential energy as the ball moves upward against the force of gravity until it reaches its maximum height.

C) The thermal energy of the ball is converted to chemical potential energy.

This option is incorrect as it misrepresents the types of energy involved. The situation does not include any conversion between thermal and chemical potential energies, as the primary focus is on kinetic and gravitational potential energy.

D) The chemical potential energy of the ball is converted to thermal energy.

This option is also incorrect. There is no indication that the ball possesses chemical potential energy in this context, nor is there a conversion to thermal energy occurring during the upward motion of the ball.

Conclusion

The correct option, B, accurately describes the energy transformation occurring as the ball moves upward. The kinetic energy from the initial strike is converted into gravitational potential energy, which is the fundamental concept being tested. All other options fail to align with the physical principles governing the motion of the ball in this scenario.
