Trabajo Mecánico y de Energía

¿Qué es el término trabajo?

Es común asociar el término trabajo con la realización de una actividad física.

En física, el trabajo mecánico es una forma en que se transfiere energía de un cuerpo a otro. Si consideramos que una fuerza (F) actúa sobre un cuerpo en la misma dirección y sentido de su desplazamiento ( ΔX):

El trabajo mecánico (W) puede ser expresado matemáticamente como el producto de estas dos magnitudes:

W = F • ΔX

¿Cuándo una fuerza realiza un trabajo?

• Cuando la fuerza actúa en la misma dirección y sentido del desplazamiento, el trabajo que realiza tiene un valor positivo (W > 0).
• Cuando la fuerza actúa en la misma dirección pero en sentido contrario al desplazamiento, el trabajo que realiza tiene un valor negativo (W < 0).
• Cuando la fuerza actúa en dirección perpendicular al desplazamiento, no realiza trabajo (W = 0).
