Question 3

Chemical potential energy is converted into kinetic energy.

As the electric golf cart is driven on a flat road, the chemical potential energy stored in the batteries is converted into kinetic energy that propels the cart forward.

A) Elastic potential energy is converted into thermal energy.

This option is incorrect because elastic potential energy typically pertains to objects that can be deformed (like springs) and is not relevant in the context of an electric golf cart. There is no mechanism in the golf cart that converts elastic potential energy into thermal energy while driving.

B) Gravitational potential energy is converted into thermal energy.

This option is also incorrect. Gravitational potential energy pertains to an object's height relative to the ground and is not a factor when driving on a flat road. In this situation, there is no conversion of gravitational potential energy taking place.

C) Thermal energy is converted into elastic potential energy.

This option is incorrect as well. Thermal energy is not being converted into elastic potential energy in the operation of an electric golf cart. The primary energy source for the golf cart is the battery, which does not involve elastic potential energy in its function.

D) Chemical potential energy is converted into kinetic energy.

This option is correct because the electric golf cart's batteries store chemical potential energy, which is converted into kinetic energy to drive the cart forward. This is the fundamental energy transformation that occurs during the operation of an electric vehicle.

Conclusion

The correct answer, which identifies the conversion of chemical potential energy into kinetic energy, accurately describes the primary energy transformation occurring in the golf cart as it moves. Other options fail to relate to the energy processes relevant in this scenario, as they either misapply the concepts of energy conversion or pertain to unrelated forms of energy.
