The object I chose was a person I couldn't put the picture. The car has a net force of 0n because it has a balanced force. This means that if The person has a gravitational force of 20n the normal force will be 20n because the same force that is pulling it to the center of the earth is also pushing it off the ground.
An object that has an Unbalanced force is an egg falling off a tree. This object is unbalanced because there is no force that is pushing it up so there is not an normal force the only force that it has is gravitational force because its going doen to the center of the earth until something stops it.
Next time you can put a link to the page with the picture on it! :D 3/3
