Question

balanced forces
when two forces are equal and opposite, they cancel each other out. the net force is 0 n. if the object is still, it stays still. if it is moving, it keeps moving at the same speed.
unbalanced forces
when one force is stronger than the other, they do not cancel out completely. this creates a net force. this causes acceleration—meaning the object will speed up, slow down, or turn.
calculating net force
the rule:

• same direction: add the forces together.
• opposite direction: subtract the smaller force from the larger one.

look at the scenarios below. calculate the net force and determine the direction of movement.

scenario	calculation	net force & direction
team a pulls left with 200 n. <br> team b pulls right with 200 n.

Explanation:

Step1: Identify force directions

Forces are opposite (Left/Right), equal magnitude.

Step2: Calculate net force

$200\ \text{N} - 200\ \text{N} = 0\ \text{N}$
