Explore the concept of gravitational potential energy (PE) and the forces acting against gravity. Learn about the downward acceleration of an object released from a height and how energy transformation occurs. As potential energy is converted into kinetic energy (KE), observe that the total energy remains constant. This lecture discusses essential principles such as the work done to build up potential energy, the force due to electric fields, and how these concepts interrelate. Includes visual aids for better understanding.
