What is an example of positive work?

What is an example of positive work?

When force and displacement are in the same direction, the work performed on an object is said to be positive work. Example: When a body moves on the horizontal surface, force and displacement act in the forward path. The work is done in this case known as Positive work.

What are the four types of work?

What are two work examples?

Examples: Pushing a car horizontally from rest; shooting a bullet (the powder does the work); walking up stairs; sawing a log.

What is positive and negative work done?

Positive work follows when the force has a component parallel to the displacement. Positive work adds energy to a system. Negative work follows when the force has a component opposite or against the displacement. Negative work removes or dissipates energy from the system.

Can work done be negative?

Work can be either positive or negative: if the force has a component in the same direction as the displacement of the object, the force is doing positive work. If the force has a component in the direction opposite to the displacement, the force does negative work.

What are three aspects of professionalism in healthcare?

What is the example of zero work?

1) A simple example of zero work is when you stand holding a bag in your hands and do not move it. Your hands apply a force on the bag to balance the force of gravity exerted on it but since there is no displacement of the bag, the work done on it by you (your force) and also the gravity is zero.

What are the examples of zero work done?
