Question
A force of 50 N is applied to move an object a distance of 4 m. Calculate the work done on the object Explain your answer using Work done by a force and work done.
Answer
200 J
Explanation
A strong answer should address calculate distance from work done and force 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
Common Mistake in Calculating Distance
Students often confuse the formula for calculating distance, mistakenly using distance = work done / force instead of correctly applying the rearranged formula.
To fix this, remember that distance can be calculated by rearranging the work done equation W = F x s to s = W / F. Always ensure you are using the correct formula for the calculation.
