SUMMARY
Newton's 2nd Law can be derived for a single body in one-dimensional motion using the principle of conservation of energy. The equation F = m(du/dt) represents the force as the product of mass and the acceleration (the derivative of velocity with respect to time). The conservation of energy principle asserts that the total energy remains constant over time, leading to the conclusion that the rate of change of energy is zero. This foundational concept is crucial for understanding the dynamics of motion in physics.
