Question on: SS1 Physics - Work, Energy, And Power

The conservation of mechanical energy is a fundamental principle in physics that states that the total mechanical energy of a closed system remains constant as long as no external forces are acting on it. Mechanical energy is the sum of an object's kinetic energy and potential energy. Kinetic energy is the energy of motion, while potential energy is the energy associated with an object's position or configuration.

According to the conservation of mechanical energy, the total mechanical energy at one point in a system is equal to the total mechanical energy at any other point, provided no external forces, such as friction or air resistance, are acting on the system. This principle holds true for a wide range of systems, including simple pendulums, roller coasters, and projectile motion.
