Homework Statement
F=ma can be written as F=ma(along x, y or z-direction, )
when applying this equation along say horizontal x direction, the direction of acceleration needs to be taken as it is a vector.
i mean say 2 forces of 5 N and 3 N are applied on a 2 kg body that moves towards left as 5 N is applied towards left and 3N towards right. Now
According to me ,
5-3=2(-a)
= 2=-2a
=-1 m/s^2=a
this -1 indicates that accn is towards left.
I am confused with the idea should eqn be 5-3 = -2a or 5-3 =2a. i would go with the former one.
