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

Click For Summary
SUMMARY

This discussion confirms that Newton's laws are applicable to component forces and resultant acceleration. Specifically, when analyzing forces along different axes, the equations Ʃfx=0 and Ʃfy=0 can be utilized to resolve forces into their components. The resultant acceleration can then be calculated using the formula Ʃf=ma, demonstrating that both component vectors and resultant forces contribute to acceleration.

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.
