What is the energy of an object because of its potential and kinetic energies?
Abin is doing work by lifting a bowling ball. Which statement could be made about the energy in this situation?
When Anna eats an apple, the sugars in that apple are broken down into the substance called glucose. Glucose is then burned in her body for energy. One of the body parts that needs this energy is the heart, which beats due to electrical impulses. A byproduct of this glucose breakdown is the heat that warms her body and is later released.
Johanna is studying what happens to the energy as a ball rolls down a ramp. What is one form of energy that she is studying?
