Can there be a displacement of any object in the absence of any external force?

Can there be displacement of an object in the abence of any force acting on it ? Think. Discurss this question with your friends and teacher.

Show that the total linear momentum of a system of particles is conserved in the absence of any external force. Also show that total linear momentum of the system is equal to the product of the total mass of the system and the velocity of its centre of mass.

A part of Newton's first law states that a body continuous to move uniformly in the absence of an external force appears contradictory Comment.

Statement-1 : Total linear momentum of system in centre of mass frame is zero only when there is no net external force. Statement-2 : Total linear momentum of system is conserved in absence of net external force.

A force of 7N acts on an object. The displacement is, say 8m, in the direction of the force, Let us take it that the force acts on the object throughout the displacement. What is the work done in this case ?

Why can current persist in a superconductor in the absence of any applied voltage ?

Can kinetic energy of a system be increased without applying any external force on the system?

When a body is spinning on its axis in absence of any external torque, then choose the wrong statement
