FUERZAS CONSERVATIVAS y NO CONSERVATIVAS.

Introduction to Conservative and Non-conservative Forces

In this section, the teacher introduces the concept of conservative and non-conservative forces and explains how they relate to potential energy.

Types of Forces

• Different types of forces can cause an object to move from point A to point B.

• Examples include gravitational force, electric force, and magnetic force.

Conservative Forces

• A force is considered conservative if the work done in moving an object from point A to point B is independent of the path taken.

• Examples of conservative forces include gravitational force, elastic force, and electrostatic force.

Non-conservative Forces

• Non-conservative forces are those for which the work done depends on the path taken.

• Examples of non-conservative forces include frictional force and normal force.

Relationship between Conservative Forces and Potential Energy

This section explores how conservative forces are related to potential energy.

Energy Associated with Conservative Forces

• When a conservative force acts on an object (e.g., gravitational or electrostatic), it is associated with a position-dependent energy called potential energy.

• For example, gravitational potential energy exists when gravity acts on an object.

Work Done by Conservative Forces

• The work done by a conservative force is equal to the negative change in potential energy.

• Mathematically, it can be expressed as:

• Work = -(Change in Potential Energy)

• Or equivalently: Work = (Potential Energy at Initial Position) - (Potential Energy at Final Position)

Conservation of Energy

• When conservative forces act on an object, the work done does not get lost but rather gets stored as potential energy.

• There is a relationship between potential energy and kinetic energy that will be explored further in conservation of energy problems.
