Question: 1-39
To bring heavy boxes down a flight of stairs, Tyrone uses a ramp. He slides the boxes down the ramp. The movement transforms one type of energy into two other forms. Which of the following uses the way that most of
the energy is transformed?
O potential energy into chemical energy and mechanical energy
O potential energy into light energy and mechanical energy
O potential energy into sound and chemical energy
potential energy into heat and kinetic energy

Answer 1

The correct answer is option is - potential energy into heat and kinetic energy

Step-by-step explanation:

Potential energy is an energy that is stored in an item or substance that is transformed into another form of energy according to the law of conservation of energy that states the energy can not be created or destroyed but only transform from one form to another.

Whenever an object moves from a stable state the energy that is found in the object is known as the kinetic energy, it is also called the energy of a moving object.

In this case, the potential energy of the boxes transform into kinetic energy as it comes down from the ramp, this conversion also releases heat if friction is available.
