The forces of friction, which oppose displacement, also carry out work when a body is moving. The work of friction is converted into heat. The greater the force of friction, the more force must be exerted to move the body. Verify how friction affects the displacement of some blocks.
TEACHING OBJECTIVES :To understand what is a friction force and how it affects the movement of a body. Quantifying the value of work that develop the forces acting on an object in the presence and absence of friction.
PREVIOUS KNOWLEDGE: Concept of force.
METHODOLOGY : Conceptual and procedural in a virtual environment.
