Desribe precisely and concisely in 4 to 6 sentences the steps necessary to find the resultant magnitude and direction of two or more vectors

Solutions

Expert Solution

Two pieces of information are required to describe a vector -- its maginitude (size) and its direction (tilt).

This information may be stated graphically or algebraically. When stated algebraically vectors may be given in either rectangular form, (x,y), or polar form, r and .

  • Rectangular form, (x,y), says:
  • start at the origin,
  • go the required distance in the x direction (the x-component of the vector), then
  • go the required distance in the y direction (the y-component of the vector), then
  • stop, and
  • consider the LENGTH AND DIRECTION OF THE SHORTCUT FROM START TO FINISH as the vector.
  • Polar form, r , says:
  • start at the origin,
  • go in the required direction (the direction of the vector),
  • go for the required distance (the magnitude of the vector), then
  • stop, and
  • consider the LENGTH AND DIRECTION OF THE PATH FROM START TO FINISH as the vector.
