Easier to pull a lawn roller than to push it, Physics

Assignment Help:

Explain why easier to pull a lawn roller than to push it?

Explaination:

In Pulling,

effective weight of lawn mover= mg-fsinx

In pushing,

effective weight = mg+fsinx

The force applied to move a body depends upon effective weight. As effective weightin the case of pulling is less than in the pushing , so less force is required in pulling. Hence, it is easier to pull than to push.
