1.	It is easy to pull than to push a lawn roller.why?
Answer» It is easier to pull a lawn roller than to push it. Explain using the resolution of forces. Answer: 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.
