Al and Ben are on roller skates and Al rolls into Ben. Al exerts a force of 30 N on Ben when they collide. Explain what force Ben exerts on AI.

Reaction force

Explanation:

Newton´s 3rd law says that every force exerted in nature has an equal and opposite force.

For example here, when Al exerts force on Ben, Ben exerts the same amount of force (30N) on Al.

Al exerts the action force and Ben exerts the reaction force.
