Question

select the correct answer. which unit abbreviation is a measurement of force? a. m/s b. m/s² c. n d. n/s

Explanation:

• Option A: \( \text{m/s} \) is the unit of speed or velocity (distance per unit time), not force.
• Option B: \( \text{m/s}^2 \) is the unit of acceleration (rate of change of velocity), not force.
• Option C: \( \text{N} \) (Newton) is the SI unit of force. By Newton's second law \( F = ma \), where mass (\( m \)) is in kilograms and acceleration (\( a \)) is in \( \text{m/s}^2 \), the unit of force is \( \text{kg·m/s}^2 \), which is defined as a Newton (\( \text{N} \)).
• Option D: \( \text{N/s} \) is a unit of rate of change of force (force per unit time), not a unit of force itself.

Answer:

C. N
