What is the definition of a push force?

A push force is defined as a force that moves an object away from oneself. This action involves applying a force in the direction opposite to the object of interest, causing it to accelerate away from the source of the force. For instance, when you push a box across the floor, you exert a push force that propels the box outward from your body.

In contrast, the alternative definitions do not accurately encapsulate the nature of a push force. A force that moves an object toward oneself describes a pull force, and thus does not represent a push. The description of a force as having no effect on an object contradicts the fundamental concept of force, as forces are meant to cause changes in motion. Lastly, defining a force that only acts in a downward direction incorrectly suggests that forces are limited to a specific orientation rather than acknowledging that forces can act in various directions based on the context.
