Choose the INCORRECT statement (with respect to the `2`nd law of motion)

A

Any internal force in the system are not included in net force while equation

B

Acceleration here and now is determined by the force here and now and not by any history of the motion of the particle.

C

In the second law, `F=0` implies `a=0`. The second law is obviously consistent with the first law

D

if a force is not parallel to the velocity of the body, but makes some angle with it, it changes only component of velocity along the direction perpendicular to direction of force.
