Newton's SECOND law states:
AF = mv
BF = ma (net force = mass × acceleration)
CF = ½mv²
DF = mgh
Answer & Solution
Correct answer: B. F = ma (net force = mass × acceleration)
Net force on an object equals its mass times its acceleration: F⃗ = ma⃗. The direction of acceleration is the same as net force. SI unit of force: newton (1 N = 1 kg·m/s²).
