Question
State that one joule is equivalent to one newton metre.
Answer
One joule is defined as the amount of work done when a force of one newton moves an object through a distance of one metre in the direction of the force.
Explanation
This question assesses the student's ability to recall a fundamental definition in physics, linking the concepts of work, force, and distance. It is a basic yet essential concept in understanding energy and work done.
Common mistake
Misunderstanding Work Done Against Friction
Students often confuse the concept of work done against friction with the total energy transferred, failing to recognize that this work specifically results in energy being transferred to thermal stores.
To fix this, students should focus on the definition of work done as energy transferred when a force moves an object, and specifically understand that work done against friction leads to an increase in thermal energy.
