One aspect of Newton's first law is that an object at rest tends to stay at rest. This can be seen in the reluctance of the objects on the table to be moved as the cloth is pulled out from under them. Some frictional force exists between the cloth and the objects, which exerts a torque that, if strong enough, will rotate and topple the object.

Its because of the Inertia. Newton's first law of motion states that "An object at rest will remain at rest and an object in motion will remain at motion unless acted upon by an external or unbalance force.
