Are Newton's Laws Applicable to Component Forces and Resultant Acceleration?

[Mdhiggenz]

Homework Statement

I just wanted to know if I was correct, when dealing with a Newton law problem that has components.

Ʃfx=0 and ƩfY = zero

However when we add the forces together then we can use Ʃf=ma

thanks

1. All forces can be resolved into components whatever axis you choose.
2. Component vectors also produce acceleration. Vector addition or subtraction produces the resultant acceleration.

Thus it is applicable, f=ma for components or resultant forces.
