Which of the following is the correct representation of the unit of energy? (2019)
Step 1: Understand what energy is. Energy is the ability to do work.
Step 2: Learn about units of energy. The most common unit of energy is the Joule (J).
Step 3: Know that a Newton (N) is a unit of force. One Newton is the force needed to accelerate 1 kilogram of mass at 1 meter per second squared.
Step 4: Understand the relationship between work and energy. Work is done when a force moves an object. The formula for work is: Work = Force x Distance.
Step 5: Realize that when you use the formula for work, if you use Newtons for force and meters for distance, the result is in Joules. This means 1 Joule = 1 Newton x 1 meter.
Step 6: Conclude that Joules and Newton-meters are equivalent because they both measure the same thing: energy.
