\nDuring free fall of an object, its potential energy decreases and its kinetic energy increases.
\n<\/section>\n
\n– Free fall is defined as motion under the influence of gravity only.
\n– Potential energy (PE) due to gravity is given by mgh, where m is mass, g is acceleration due to gravity, and h is height. As an object falls, its height (h) decreases, so its potential energy decreases.
\n– Kinetic energy (KE) is given by 0.5mv\u00b2, where m is mass and v is velocity. As an object falls under gravity, its speed (v) increases (due to acceleration ‘g’), so its kinetic energy increases.
\n– In ideal free fall (neglecting air resistance), the total mechanical energy (PE + KE) is conserved. The decrease in potential energy is equal to the increase in kinetic energy.
\n<\/section>\n
\nIf air resistance is considered, some of the potential energy is converted into heat and sound energy due to air friction, and the increase in kinetic energy is less than the decrease in potential energy. However, the question refers to ‘free fall’ which typically implies ideal conditions unless specified otherwise.
