During takeoff, the aircraft acquires potential energy, which is soon replaced by kinetic energy. When the plane is at the lowest point of the inclined plane, part of its potential energy, stored by the body ascending to the height, is converted into the energy of the moving body. The other part is working against the frictional force. Kinetic energy is directly proportional to body weight and speed.
