The object will remain at rest until a certain force is applied to it. If the object is very heavy, then it will take a lot more effort and more force before it can be moved from its position. Take note that there are some objects that will be easier to move like the ball.
A ball is very easy to move because it does not have any edges. Even the slightest push will be enough to make it move. It will only be confined to a small space when it is surrounded by walls. Take note that all objects can be at rest. A lot of the inanimate objects that you have at home right now are not moving.
