An apple held above the ground has potential energy. As the apple falls, this potential energy is converted to kinetic energy. Finally, the apple hits the ground and stays there. What has happened to the energy? The energy goes to producing sound and to heating the ground, apple, and surrounding air.
It is transformed back into gravitational potential energy.
The apple keeps the energy inside it in the form of mass-energy.
The energy goes into the ground, and as a result, the orbit of the Earth about the Sun is slightly changed.

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
