In solving force problems, is it better to work with the vector form of Newton's 2nd law F = mã or with the component versions [F₂ = max and Σ Fy = may? work with the vector version because vectors are really easy to work with work with the component versions because they are scalar equations work with either version because they are both really easy to work with

please help me with this physics question!! thank you
Transcribed Image Text:In solving force problems, is it better to work with the vector form of Newton's 2nd law ΣF = ma
or with the component versions Σ F = mag and Σ Fy
=
may?
work with the vector version because vectors are really easy to work with
work with the component versions because they are scalar equations
O work with either version because they are both really easy to work with
Transcribed Image Text:When filling in the x-components of the forces in F, when do you use + signs and when do you
use - signs?
Use a + sign when a force's x-component points in the +x direction for your coordinate system, and use a -
sign when it points in the -x direction.
Use a + sign for every force's x-component because means "add."
Use a + sign for every force's x-component because magnitudes are always positive.
