Energy changes in a system, and the ways energy is stored before and after such changes

Question

A. Energy is conserved and remains unchanged
B. Kinetic energy is converted to thermal energy
C. Gravitational potential energy is converted to kinetic energy
D. Energy is lost to the environment without any conversion

Answer

Kinetic energy is converted to thermal energy

Explanation

When a moving object collides with an obstacle, its kinetic energy is often transformed into thermal energy due to friction and deformation.

Common mistake

Misunderstanding Energy Redistribution

Students often confuse the concept of energy redistribution with energy conservation, thinking that energy is lost rather than redistributed in a system.

Emphasize that energy is always conserved in a closed system; it may change forms or be redistributed, but the total energy remains constant.
