Question

Explain pulling and pushing method by vector formulation

Answer 1

Answer:

A pull is when you use force to move a thing (object) closer to you. Push DEFINE. A push is when you use force to move a thing (object) away from you. Motion DEFINE. Motion is when something (an object) is moving

Answer 2

$\huge \fbox \red{❥︎ Answer}$

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. 

Hence, it is easier to pull than to push.

 

In case of  pulling, effective weight of lawn mover = mg−fsinθ

In case of  pushing, effective weight = mg+fsinθ
