Question

Energy is transformed or energy is transferred, which statement is correct?

A. The measure of energy transfer is work

B. The measure of transformation of energy is work

C. The measure of work transfer is the kinetic energy

D. The measure of transformation of work is potential energy

Answer 1

Both are correct.

Energy transfer refers to the movement of energy from one place to another. For example light energy is tranferred from sun to earth.

Energy transformation means the changing of energy from one type to another. For example sun transforms nuclear energy into heat and light.

A. The measure of energy transfer is work. Energy can be transferred from one object to another by doing work.for exaple collision of balls.

This is true.

B. The measure of transformation of energy is work. This is false.

Since work cannot be transferred or transformed the options C and D are false.
