Dynamics

• If vectors are not in equilibrium, there is acceleration
• Resolve a vector system that's accelerating/decelerating using $f\ =$$\ ma$ in the direction of motion
• The vector version of $f=$$ma$ is:

  $\underline{F}\ =$$\ m\underline{a}$
• $\underline{F}\ =$$\ \underline{R}$
• $\underline{R}$ is the resultant force.

  
  

  Calculate $\underline{R}$ by adding all forces together
