Normal and Tangential Forces

Normal and tangential forces result from the normal and tangential accelerations that were presented in kinematics of a particle; to calculate the normal and tangential forces equations 1 and 2 would be used.

(Eq 1)  $f_n=ma_n$

m = mass

an = normal acceleration

fn = normal force

(Eq 2)  $f_t=ma_t$

at = tangential acceleration

ft = tangential force

This means that even if a particle has a constant velocity, if it is going around a curve it can still develop a normal force, and if it’s accelerating around the curve it will have a normal force along with a tangential force.
