Answer:
Yes, objects can move without external force. According to Newton's first law of motion, every object continues in the state of rest or of uniform motion unless an external force is applied to it. Therefore, the object continues to move with a constant speed when there is no force applied. Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Therefore, the velocity is not changing. If the object was already moving, then it will just keep moving. So, yes, the object can be moving when there is no force applied to it.
