Why is it easier to pull a lawn roller than to push it??
Wat an ass. Try it n see
Simple n easy.
When pushing angle bw normal and surface increases.so it is difficult to push.but incase of pulling angle is low so it is easier than pushing
In case of lawn rollers fbd in case of pushing the punshing force and mg are in same dirn so N increase s hence greater force to overcome normal is needed which is not in pulling
If we draw the free body diagram in both cases then the normal to surface will increase in pushing and decrease in pulling and we know that frictional force is the product of normal and coefficient of friction making pulling easy
