Frequently Asked Questions
In conservative systems, kinetic and potential energy convert into each other while total mechanical energy remains constant. As an object falls, potential energy converts to kinetic energy.
No, kinetic energy is always positive or zero because it depends on velocity squared. Even objects moving in the negative direction have positive kinetic energy.
In elastic collisions, kinetic energy is conserved. In inelastic collisions, some kinetic energy converts to heat, sound, and deformation. In perfectly inelastic collisions, maximum kinetic energy is lost.
The work-energy theorem states that net work done on an object equals its change in kinetic energy: W = ?KE. This connects force, distance, and energy.
This comes from integrating force over distance. Since F = ma and a = dv/dt, working through the calculus with distance gives the (1/2)mv^2 relationship.
