Sammy studied kinetic and potential energy by observing apples on a tree during a field investigation. What type of energy do the apples on the tree have?
|
|
elastic potential energy
|
|
|
mechanical energy
|
|
|
gravitational potential energy
|
|
|
sound energy
|
Explanation:
Detailed explanation-1: -The apple has gravitational potential energy. The rubber band and the spring both have elastic potential energy.
Detailed explanation-2: -The apple will fall because of gravity, so the apple on the tree has gravitational potential energy.
Detailed explanation-3: -3) When it falls down, its gravitational potential energy gradually converts into kinetic energy, but the entire enegy in the system remains same.
Detailed explanation-4: -When it falls from the tree, it starts losing its potential energy and converts it into kinetic energy as it gains speed. Thus the apple loses potential energy and gains kinetic energy.
