Work done and energy transfer
Question
- A. Work done is equal to the energy transferred.
- B. Work done is always greater than the energy transferred.
- C. Work done is always less than the energy transferred.
- D. Work done has no relation to energy transferred.
Answer
Work done is equal to the energy transferred.
Explanation
Work done is defined as the energy transferred when a force moves an object through a distance.
Common mistake
Proportional Reasoning in Work Done
Students often assume that if one braking force is twice another, the work done will also be twice, without considering the distance over which the force is applied.
To fix this, remember that work done is calculated as the product of force and distance. Ensure to compare both the force and the distance when applying proportional reasoning.
