Force And Work
... • Energy is defined as the ability to do work. • If an object has energy, it can do work by transferring the energy to another object (as one object loses energy, the other gains the same amount of energy) • Therefore the change in energy = work, and therefore the units for energy is also joules (J) ...

Chapter 8: Conservation of Energy
... There are two basic properties of the conservative forces that are related to the work done by this force. These are: • If the work done by the force is independent of the path, the force is said to be a conservative force. Otherwise, it is nonconservative. • The work done by a conservative force in ...

... The result F = -dU/dx is useful not only for computing the force but also for visualizing the stability of a system from the potential energy plot. Suppose there is a force on the particle is F = -dU/dx, and the system is in equilibrium where there is no force i.e. dU/dx = 0. If this occurs at a min ...
