Question

As a person pushes a box across a floor, the energy from the person’s moving arm is transferred to the box, and the box and the floor become warm. During this process, what happens to energy?

It is increased.
It is conserved.
It is decreased.
It is created.

Answer 1

Answer:

It Is Converted.

Explanation:

The Frictional force of the Box is Converted into Heat Energy

Answer 2

The correct answer :  It is conserved

Explanation

• When the box is moved over the floor, both the floor and the box warm up, simulating an energy conservation situation.
• The idea of energy conservation can be used to tackle the given issue. According to the definition of energy conservation that Energy is not generated nor destroyed; rather, it is transformed from one form to another.
• In the example problem, the person pushes the box across the floor, transferring mechanical energy from the moving arms of the person to the box, warming both the box and the floor in the process.
• Kinetic energy from the moving arm of the individual is transmitted to the box during this operation. And as a result, kinetic energy is converted to thermal energy or heat energy, which causes the box and floor to warm up.

Hence the energy is conserved
