Answer :
The mechanical energy of the shuttle-earth system when the shuttle lands less than when it is in orbit.
What kind of energy is mechanical?
The energy of an object in motion or the energy stored in an object due to its position is known as mechanical energy (also known as kinetic energy or potential energy). Renewable energy sources also rely on mechanical energy to operate. Many renewable energy sources rely on mechanical energy to sufficiently generate electricity or convert energy.
At motion or in a certain position in relation to the surface, objects contain mechanical energy. For instance, a box placed vertically above the ground will only have potential energy. Due to its motion, a moving object has mechanical energy, often known as kinetic energy.
