Friction — Pushing vs PullingHardQuestion 30233

Question

A block is pushed at angle θ below horizontal vs pulled at angle θ above horizontal. In which case is it easier to move (less applied force needed)?
  1. A
    Pushing
  2. B
    Pulling
    Correct
  3. C
    Both equal
  4. D
    Depends on μ only

Correct answer

Pulling

Explanation

Pulling: the upward component reduces N → reduces friction. Pushing: the downward component increases N → increases friction. Pulling requires less force.
