To determine the correct condition for doing work in physics, we need to analyze the definition of work.

In physics, work is defined as the product of the force applied to an object and the distance over which that force is applied, specifically in the direction of the force. The mathematical expression for work $$ W $$ is given by:

$$
W = F \cdot d \cdot \cos(\theta)
$$

where:
- $$ W $$ is the work done,
- $$ F $$ is the magnitude of the force applied,
- $$ d $$ is the distance moved by the object in the direction of the force,
- $$ \theta $$ is the angle between the force and the direction of motion.

From this definition, we can conclude that:

1. **Only applying force to an object** does not constitute work unless there is movement.
2. **Only moving the object through some distance** does not constitute work unless a force is applied.
3. **Causing the object to change direction** does not constitute work unless there is a component of force in the direction of the movement.
4. **Applying a force to an object over some distance** is the correct condition for doing work, as it involves both force and movement in the direction of that force.

Thus, the correct answer is:

**Apply a force to an object over some distance.**
To do work in physics, you must apply a force to an object over some distance.
