resultant forces

• what happens when forces are acting in different direction?

  some are going to cancel each other out
• what is resultant force?

  the overall single force of an object after the multiple different forces have been cancelled out
• how do you figure out free body diagrams?

  1. first subtract to get the vertical component of newtons
  2. now subtract to get the horizontal component of newtons
  3. if both the vertical and horizontal component = 0, there is no resultant force meaning the object is balanced in equilibrium
• how you figure out the resultant force on a scale drawing?

  1. put the forces in the graph tip-to-tail
  2. draw a line from the starting point to the end point and measure with a ruler to find the resultant force
• how do you figure out the direction of the force on a scale drawing?

  1. complete the resultant force
  2. measure the angle
