When an object is stationary, the forces acting on it are balanced. These forces could include gravitational force, normal force, frictional force, and any other external forces. The net force on the object is zero, resulting in no acceleration and the object remaining at rest.

The forces that act on a stationary object are typically the gravitational force pulling the object down and the normal force exerted by the surface supporting the object.
external forces act on the objects in the system.
False. Forces can also change the direction and speed of objects in motion, in addition to stopping them.
Forces act on all objects with mass. This includes everyday objects like books, cars, and furniture, as well as celestial objects like planets and stars. Forces can cause objects to move, accelerate, deform, or rotate.
Two examples of objects that are similar in that forces can act without objects touching are magnets and electric fields. In both cases, forces can act at a distance without direct contact between the objects.
