alleryStart learning →The SI unit of force is the newton. One newton equals:
A10 kg multiplied by 10 m per second
B1 g multiplied by 1 cm per second squared
C1 kg multiplied by 1 m per second squared
D100 kg multiplied by 1 m per second
Answer & Solution
Correct answer: C. 1 kg multiplied by 1 m per second squared
1. By Newton's second law, F = m·a.
2. One newton is defined as the force that gives 1 kg an acceleration of 1 m per second squared.
3. So 1 N = 1 kg × 1 m per second squared.
4. Option B describes one dyne, the CGS unit, not the newton.
