1.15 - calculate the resultant forces that act along a line

If there is an unbalanced force, the object will accelerate in the direction of the larger force.

→ This is the resultant force.

To calculate it:

1. Look at which side has the larger force.

2. Subtract them.

→ The arrow should be pointing towards the larger side.

3. The result is the resultant force.

     5N ←◼️ → 10N

10 - 5 = 5N

Hence, the object will move forward and the resultant force is 5N.
