Question

select the correct answer. which statement about forces is true? a. forces are defined by strength but not direction. b. forces are defined by direction but not strength. c. forces are defined by both strength and direction. d. forces act only on objects that are in contact.

Explanation:

• Option A: Forces are vector quantities, so direction is essential. Eliminate A.
• Option B: Strength (magnitude) is also a key part of a force. Eliminate B.
• Option C: Forces are vectors, defined by both magnitude (strength) and direction. This is correct.
• Option D: Forces like gravity act on non - contact objects. Eliminate D.

Answer:

C. Forces are defined by both strength and direction.
