Question

Explain why it is easier to pull a roller than to push it

Answer 1

Explanation:

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

Answer 2

In pushing frictional force is greater than that of in case of pulling.The force applied to move a body depends upon effective weight . As effective weight in 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.
