Lesson 2

• Motion occurs when an object changes position over time.
• Net Force - the sum of all forces acting on an object.
• Unbalanced Forces

  • A condition when opposite forces acting on an object are not the same.
  • The net force acting on the object is not zero.
  • It causes a change in motion.
  • If the forces are moving in the same direction, add the forces. On the other hand, if opposite direction, subtract.
• Balanced Forces

  • Objects acted upon by balanced forces stay at rest or move at a constant velocity.
  • Net Force = zero
  • No change in motion
  • Understanding balanced forces helps explain the stability and motion of objects in various real-world scenarios.
