What equation is used to determine energy transfer by a force moving an object?

The equation for energy transfer when a force moves an object is stated as energy transfer (in joules) equals force (in newtons) multiplied by distance (in meters). This relationship highlights how energy is transferred in mechanical systems when an external force is applied to an object, resulting in movement.

In physics, energy is defined as the capacity to do work, and work itself is defined as the transfer of energy that occurs when a force is applied over a distance. Therefore, the amount of energy transferred is directly proportional to both the amount of force applied and the distance over which it is applied. The units in this equation align with the International System of Units (SI), where force is measured in newtons, distance in meters, and energy in joules. Thus, utilizing the correct units ensures that the energy transfer is calculated accurately.

The other options do not represent the relationship between energy transfer and the two factors of force and distance in the context of moving an object. This makes choice B the correct and most comprehensive equation for this principle.
