Question

what is a force?
the speed of an object
only a pull on an object
a push or pull that can make things move, stop, or change direction
only a push on an object

Explanation:

A force is defined as a push or pull that can cause an object to move, stop, or change direction. This is a fundamental concept in physics. The other options are incorrect because a force is not just a push or just a pull (eliminating the options that say "only a push" or "only a pull"), and "the speed of an object" is not the definition of a force.

Answer:

A push or pull that can make things move, stop, or change direction.
