Components of Net Force#

Part 1#

The image shows the free-body diagram of an object in circular motion with speed v and radius r. The net force is along the radial direction. The component of Newton’s second law along the radial direction is:

Answer Section#

• $\overrightarrow{n}+\overrightarrow{f_s}=m\overrightarrow{a}$

• $\overrightarrow{n}-\overrightarrow{f_s}=\frac{m{v}^2}{a}\overrightarrow{r}$

• $ncos(\theta )+f_s=\frac{m{v}^2}{a}$

• $ncos(\theta )-f_s=\frac{m{v}^2}{a}$

• $\overrightarrow{n_r}-\overrightarrow{f_{s,r}}=m\overrightarrow{a_r}$
