Question
A force of 50 N is applied to move an object 3 m along the direction of the force. Calculate the work done on the object Explain your answer using Work done by a force and work done.
Answer
The work done on the object is 150 J.
Explanation
A strong answer should address define work done as energy transferred when a force moves an object through a distance directly. Use the context of Work done by a force within Work done and energy transfer, then state the relevant forces or motion reasoning with units where needed. The answer is correct when it names the key physics quantity, keeps distance and displacement distinct, and links the conclusion back to the approved learning objective.
Common mistake
Confusing Work Done with Energy Transfer
Students often confuse the concept of work done with energy transfer, thinking they are the same when work done is specifically the energy transferred by a force moving an object.
To fix this, remember that work done is a specific case of energy transfer that occurs when a force causes an object to move. Focus on the definition: work done is energy transferred when a force moves an object through a distance.
