Complete the correlation: Pushing a wall without moving it : Zero work done :: Pulling a bucket of water up from a well : _____
  1. Zero work done
  2. Work done against gravity
  3. Negative displacement
  4. No force applied

Solution

Pushing a stationary wall results in zero displacement (zero work), whereas pulling a bucket upward applies force that displaces the bucket against gravity, resulting in work being done.
