### Our World of Balanced and Unbalanced Forces

## Definitions

Balanced Force- A balanced force occurs when two forces act upon a object, and are equal in size.

Unbalanced Force- A unbalanced force occurs when two forces act upon a object but are not equal in size.

## Balanced ForceAn equal force is being applied to one another in this picture. The weight of the metal block and the reaction force of the table are equal, therefore making this example balanced. | ## Balanced Force In this picture the everyday gravity around us is facing off with the force of buoyancy! These two forces are of equal strength/newton's , making this reaction balanced. | ## Balanced Force Equal forces are applied to this box, making it unable to move from it's current spot. Each person has the same amount of newton's, making this reaction balanced. |

## Balanced Force

## Balanced Force

In this picture the everyday gravity around us is facing off with the force of buoyancy! These two forces are of equal strength/newton's , making this reaction balanced.

## Unbalanced Force In the picture on the left, Charlie Brown and Linus are both on a seesaw. Because Linus weighs more than Charlie Brown, he is applying more force on his end of the seesaw, therefore making it unbalanced. | ## Unbalanced Force In this picture, there are different amounts of newton's being used. On one side, two children of 450 newton's each are playing tug of war against another child, who obviously is pulling with more newton's than the other two. The sides have a different amount of pull, therefore this is an example that is unbalanced. | ## Unbalanced Force In the picture above, a female cheerleader and a male football fan are both applying force on a beach ball. This serves as an example for an unbalanced force because the football fan has both of his arms on the ball and is pushing into the ball while the cheerleader is merely resting against it with one hand. They have a different amount of force on the ball, therefore making it unbalanced. |
