Physics Lesson 10/23

Find the X-component and y-component of all the vectors that need to be added.

Find the sum of all the x-components and all the x-components.

R_x= A_x + B_x + C_x + ...

R_y= A_y + B_y + C_y + ...

These added together give you the x-component and the y-component of the resultant.

Once you have the x-component and the y-component, you can use the Pythagorean Theorem to find the magnitude of the resultant.

R² = R_x² + R_y²

To find the direction ( $\theta$   )

 $\theta=\tan^{-1}\left(\frac{R_y}{R_x}\right)$
