以Newton's second law of motion為例, which is the general form?

1. F=ma
2. F=f(m, a)
3. http://upload.wikimedia.org/math/0/b/a/0ba118c2d8c335e2f96292a1e771bc09.png
4. F=dp/dt
5. F=m(dv/dt)


要有理由, 唔好只選慣用果個就話係

✔ 最佳答案
It should be 4. F = dp/dt
where F and p are the force and momentum of an object, and both are vector quantities.

Newton's Second Law states that the rate of change of momentum is proportional to the applied force and takes place in the direction at which the force acts.

Hece, option 4 gives the mathemtical interpretation of the law.
