When youre really, really smart

combining all the forces exerted on an object

• Forces in the Same Direction You just add
  the forces together!
• Forces in the Opposite Direction
• You subtract the larger force from the smaller
  force.

6
Balanced Forces

• Balanced Forces Produce No Change in Motion.
• The Net Force is Zero.

7
Unbalanced Forces

• Unbalanced Forces Produce a Change in Motion.
• The Net Force on the Object is Not Zero.
