Question

Which one of the following statements is not true about Newton's second law of motion$\overrightarrow{F}=m\overrightarrow{a}$?

• 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 local law.

Answer 1

The correct option is D The second law of motion is local law.

The second law of motion is a local law which means that force $\overrightarrow{F}$ at a point in space (location of the particle) at a certain instant of time is related to $\overline{a}$ 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.
