Balanced and Unbalanced forces

Blanced Force~if a force is balanced, the speed will remain the same so their is no change

Unbalanced Force~this force will cause a change in speed,direction, or even both in an object.

Think of a tug-a-war game. When you a person says go, both teams will start to pull in opposite directions. The middle of the rope doesn't go anywhere because the forces on both side are the same. As you keep playing, eventually one side will have a greater force so the rope stats leaning towards their direction. That means the forces became unbalanced. Acceleration will have caused the team that has own to have a greater force

Net force~a measure of force on an object(usually in newtons)

Velocity~ a measure of speed of an object that is moving in a certain direction

An example of a balanced force is two football players. At the same time they will start pushing against each other but neither of them are moving. That means they are using the same amount of force on each other to keep them from moving.
