Question

A student wraps a metal sheet around a copper wire. She then hammers the metal sheet several times. The temperature of the sheet rises, and it becomes even flatter. Which type of energy transformation does the example involve?

A. kinetic energy into heat energy
B. kinetic energy into chemical energy
C. potential energy into heat energy
D. potential energy into chemical energy

Answer 1

Answer: Kinetic energy into heat energy.

Step-by-step explanation:

We know that they temperature of the metal sheet increases, this means that there is heat energy. When the hammer strikes the metal sheet, this is known as kinetic energy, because it is striking.

Thus, the only option is kinetic into heat energy.
