Question

"It's easier to pull to a lawn mower than to push it. Explain with the help of a vector diagram.

Answer 1

The force applied to move a body depends upon effective force applied on it including its weight.

As effective weight in the case of pulling is less than in the pushing, less force is required in pulling.

Hence, it is easier to pull than to push.

In case of pulling, effective weight of lawn mover = $mg-fsin\theta$

In case of pushing, effective weight = $mg+fsin\theta$
