We must __________ forces to calculate net force if the forces are going in OPPOSITE directions.
Virty [35]

Answer:

subtract

Explanation:

To find the net force of two bodies going in opposite directions, we must subtract the forces this is because they are not additive forces.

  • The net force is the resultant force acting on a body.
  • This resultant force is the single force that will produce the same effects as all given forces.
  • When forces are directed oppositely on a body, they are subtracted from each other to find the net force.
