Solution
- Yes, there can be displacement in an object in the absence of force. If the object is moving at a uniform speed, then no external force acts on that object, but there is displacement in the object.
- When an object is released in a free state from an inclined plane, it comes down due to the force of gravity, but on reaching the earth's surface, no force acts on it in the horizontal direction.
- That object moves at a uniform speed in the horizontal direction, and displacement keeps occurring in it.
