Formula: net = F₁ + F₂ + F₃ (with signs)

Step-by-Step Breakdown

1. Values used:

2. Force 1 (right +) = 30 N

3. Force 2 = -10 N

4. Force 3 = 5 N

6. Net force = 25N

The math behind it

Add forces along a line using signs for direction. A zero net force means the object is in equilibrium.

30 N right and 10 N left → 20 N net to the right.

What if the net force is zero?

The object stays at rest or moves at constant velocity (Newton's first law).
