Kinetic Energy and Conservation: How Forces Shape Motion and Work
This PowerPoint covers kinetic energy and the conservation of mechanical energy. It introduces kinetic energy as the ability to do work, illustrated by an example of a weight hitting a nail. The presentation explains the relationship between kinetic and potential energy, particularly how the kinetic energy of a falling object is equal to the potential energy it loses. Conservation of mechanical energy is discussed, where the total energy (kinetic + potential) remains constant in a system, such as in a projectile or spring. Non-conservative forces, like friction, are also covered, noting that they don′t conserve mechanical energy. Escape velocity and orbital velocity are explained, showing the energy differences needed to escape Earth′s gravity or maintain an orbit.
