Question

check for understanding: drag the action and reaction labels by the correct arrow in each picture. 1. boy sitting in a chair action force reaction force 2. blue car collides into white cart action force reaction force

Explanation:

According to Newton's third law of motion, for every action, there is an equal and opposite reaction. In the first case, the boy exerts a downward force (action force) on the chair due to his weight, and the chair exerts an upward force (reaction force) on the boy. In the second case, the blue car exerts a forward - directed force (action force) on the white car when it collides, and the white car exerts a backward - directed force (reaction force) on the blue car.

Answer:

1. The red arrow (downward) is the action force (boy's weight pushing down on the chair), and the blue arrow (upward) is the reaction force (chair pushing up on the boy).
2. The red arrow (forward) is the action force (blue car pushing on white car), and the blue arrow (backward) is the reaction force (white car pushing back on blue car).
