Question

1. which of these statements are true about action and reaction forces? a. they are exerted in the same direction. b. they are exerted on different objects. c. they have the same magnitude. d. they are exerted in opposite directions.

Explanation:

According to Newton's third law of motion, action - reaction forces act on different objects. They have equal magnitudes and opposite directions.

• Option A: Action - reaction forces are not in the same direction.
• Option B: They act on different objects. For example, when you push a wall (action force on the wall), the wall pushes you back (reaction force on you).
• Option C: Magnitudes of action - reaction forces are equal.
• Option D: Directions of action - reaction forces are opposite.

Answer:

B. They are exerted on different objects, C. They have the same magnitude, D. They are exerted in opposite directions.
