Understanding motion is easier when we look at balanced and unbalanced forces.

Balanced Forces:

• Balanced forces happen when two forces are the same size but push in opposite directions.

• When this happens, we say the net force is zero (or $F_{net} = 0$).

• This means that the object either stays still or moves at a steady speed.

• A good example is when you push against a wall. You aren't going anywhere because the forces are balanced.

Unbalanced Forces:

• Unbalanced forces occur when the forces do not cancel each other out.

• This means there is a net force acting on the object (or $F_{net} \neq 0$).

• When this happens, the object speeds up in the direction of the stronger force.

• For instance, think about kicking a soccer ball. Your kick is stronger than the ball just sitting there, so it rolls away!

In short, balanced forces help keep things steady, while unbalanced forces make things change and move!
