Energy vs. Force: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on January 11, 2024
Energy is the capacity to do work or cause physical change; force is a push or pull acting upon an object.
Key Differences
Energy is a measure of the ability to do work, like moving an object or heating something up. Force, on the other hand, is an interaction that changes the motion of an object. Energy can be stored, but force must be applied.
In physics, energy takes various forms like kinetic or potential, each representing a different kind of work. Force, however, is always a direct interaction, like gravity or friction, affecting how an object moves or is held still.
Energy is quantified in units like joules or calories, showing how much work can be done. Force is measured in newtons, indicating how much push or pull an object experiences.
Energy can be transferred or transformed, like from chemical to mechanical. Force is not transferred; it is the direct cause of movement or deformation.
Energy and force are closely related in physics, with force often involved in the transfer or transformation of energy, yet they are distinct concepts.
