Which one of the following statement is not ture about Newton's second law of motion `vec(F)=vec(ma)` ?

Options

A. The second law of motion is consistent with the first law
B. The second law of motion is a vector law.
C. The second law of motion is applicable to a single point particle.
D. The second law of motion is not applicable to a single point particle.

Answer

D

Explanation

The second law of motion is a local law which means that force `bar(F)` at a point in space (location of the particle) at a certain instant of time is related to a at that point at that instant. Acceleration here and now is determined by the force here and now, not by any history of the motion of the particle.
