|
|
Yes, because an object at rest stays at rest until an outside force causes it to move.
|
|
|
No, because an object at rest has a tendency to change of position by the force of gravity.
|
|
|
Either A or B
|
|
|
None of the above

Detailed explanation-1: -Force can make a body that is at rest to move. It can stop a moving body or slow it down. It can accelerate the speed of a moving body. It can also change the direction of a moving body along with its shape and size.
Detailed explanation-2: -Newton’s first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.
Detailed explanation-3: -If an object is at rest, then there are no forces acting upon the object. It would take an unbalanced force to keep an object in motion at a constant velocity.
Detailed explanation-4: -Newton’s First Law is the law of inertia. An object with no net forces acting on it which is initially at rest will remain at rest. If it is moving, it will continue to move in a straight line with constant velocity.
