Conservative Internal Forces and Work Done
Conservative internal forces are those forces that do not depend on the path taken by a system but only on its initial and final positions. Examples include gravitational and elastic forces. These forces can do work on a system, and this work can either be positive or negative.
Negative Work Done and Change in Energy
When conservative internal forces do negative work on a system, this means that the system has gained energy. Conversely, when they do positive work, the system loses energy. This is because the work done by these forces is converted into potential energy, which is stored in the system.
The negative of the work done by conservative internal forces on a system equals the change in potential energy of that system. Mathematically, this can be expressed as follows:
W = -ΔU
Where W is the work done by the conservative internal forces, and ΔU is the change in potential energy of the system.
Implications of the Equation
The above equation has some important implications:
- If the work done by the conservative internal forces is negative, then the change in potential energy is positive, which means the system has gained energy. This can happen, for example, when an object falls under the influence of gravity.
- If the work done by the conservative internal forces is positive, then the change in potential energy is negative, which means the system has lost energy. This can happen, for example, when an object is lifted against gravity.
- If the work done by the conservative internal forces is zero, then the change in potential energy is also zero, which means the system's energy remains constant. This can happen, for example, when an object moves along a horizontal surface.
Overall, the equation W = -ΔU is a useful way to understand the relationship between conservative internal forces, work done, and changes in potential energy.
