Question

Using free body diagram, show that it
is easy to pull an object than to push it.​

Answer 1

Diagram .

Pulling is easier than pushing as there is less normal reaction and hence there is less friction in case of pull . Friction has to be taken into consideration while we are studying the push and the pull of the body .

Answer 2

For a short object, it is easier to pull than push !

Let see the physics of this problem :

• First of all, the friction on an object is expressed as :

$f = \mu \times N$

$\boxed{ \implies f = \mu \times (mg)}$

• Now, when a short object is being pulled, a component of pull (i.e. sine component) reduces the normal force (N) on the object.

• The new value of N becomes $mg - F\sin(\theta)$

So, new friction becomes :

$\boxed{ \implies f_{new} = \mu \times \{mg - F \sin( \theta) \}}$

$\boxed{ \implies f_{new} < f}$

So, when we are pulling , the friction is getting reduced making it easier to move the body.
