Question

which of these is true about forces?forces can be seen.forces are a form of matter.forces can be touched.forces act in pairs.

Explanation:

• "Forces can be seen" is false because forces are not visible entities.
• "Forces are a form of matter" is false as forces are interactions, not matter (matter has mass and occupies space).
• "Forces can be touched" is false since forces are not physical objects to be touched.
• "Forces act in pairs" is true based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction, meaning forces occur in pairs.

Answer:

D. Forces act in pairs.
