Question

multiple choice 1 point
what is true about force pairs?
force pairs are always in the same direction.
force pairs are always perpendicular to each other.
force pairs are always oppositely directed.
forces dont occur in pairs.

Explanation:

According to Newton's third law of motion, for every action, there is an equal and opposite reaction. Force pairs (action - reaction pairs) always have equal magnitudes and opposite directions.

• Option 1: Force pairs are not in the same direction. For example, when you push a wall (action force), the wall pushes you back (reaction force) in the opposite direction.
• Option 2: Force pairs are not perpendicular. The action and reaction forces act along the same line of action but in opposite directions.
• Option 3: This is in line with Newton's third law.
• Option 4: Forces do occur in pairs as per Newton's third law.

Answer:

Force Pairs are always oppositely directed.
