Explain why it is easier to pull a lawn mower than to push it.

Explanation

The force F is usually applied obliquely relative to the ground. During either a push or a push or a pull of the lawn mower [Fig.2.91].

cases the force F is resolved into two components one is horizontal and the other is vertical . The horizontal component H of the force F is responsible for the horizontal motion. The difference is, during the push the vertical componet V increases the effective weight of the mower, whereas during the pull the effective weight decrease due to V. so it is easier to pull the mower than to push it.
