What effect do pushes and pulls have on stationary objects?

The correct choice highlights that pushes and pulls can indeed shift stationary objects from their position. In the context of physics, pushes and pulls are forces that can influence an object's state of rest or motion. When a force is applied to a stationary object, such as pushing a heavy box or pulling a wagon, it can cause the object to move, indicating that such forces have a direct impact.

Understanding that stationary objects can be affected by these forces is fundamental to concepts related to motion and mechanics. For instance, an object at rest will remain at rest unless acted upon by a net external force, as stated in Newton's First Law of Motion. This principle underscores that any application of push or pull represents a net external force capable of changing the object's position.

The other choices suggest either that stationary objects are unaffected by forces or that forces can only affect objects already in motion, which does not align with the basic principles of physics regarding forces and motion. Also, suggesting that forces can change the color of an object does not relate to the physical effects of pushes and pulls, as color change typically involves chemical or optical interactions rather than mechanical forces.
