What is defined as the ability to do work?

The ability to do work is specifically defined as energy. In physics, energy is recognized as the capacity to perform work, and it exists in various forms, such as kinetic, potential, thermal, and chemical energy. When work is done, energy is transferred or converted from one form to another.

Here’s how it fits into the context of the other terms: power is often confused with energy, but it refers to the rate at which work is done or energy is transferred over time. Force is a push or pull on an object, which can cause it to accelerate and do work when applied over a distance. Torque, on the other hand, is a measure of rotational force and is also related to work in a circular motion context but does not encompass the broader definition of energy.

Understanding the distinction between these concepts is crucial, as they each play a unique role in the study of mechanics, including in applications related to brakes and other undercar systems.
