What is an object acted upon by?

An object acted upon refers to an item or entity that experiences a force or influence from an external source. This can include physical forces, such as gravity, friction, or tension, which cause the object to change its motion or state. In physics, it typically implies the object is subject to Newton's laws of motion, where the resultant forces determine its acceleration and trajectory. Essentially, it highlights the interaction between the object and the forces affecting it.
