  • Wrap-Up #1Describe one real-life situation in which a person might use the laws of motion. Do not use any of the examples given already!

  • Newtons Laws of Motion

  • Newtons Laws of Motion1st LawAn object at rest will remain at rest and an object in motion will remain in motion at a constant velocity unless acted upon by unbalanced forces

  • Newtons Laws of Motion1st LawInertia: resistance to change in motion

  • Newtons Laws of Motion1st LawInertia: resistance to change in motionAKA: momentum p = m * v

  • Newtons Laws of Motion1st LawInertia: resistance to change in motionAKA: momentum p = m * vForcesForces are balanced when they cancel each other out

  • Newtons Laws of Motion1st LawInertia: resistance to change in motionAKA: momentum p = m * vForcesForces are balanced when they cancel each other outForces are unbalanced when they do not cancel each other out

  • Wrap-Up #2For each of the following situations, determine if the forces are balanced or unbalanced:A snow skier is speeding down a mountain, going faster and fasterA snow skier is being carried up the mountain by the lift. The lift moves at a constant speed.

  • Wrap-Up #2: AnswersFor each of the following situations, determine if the forces are balanced or unbalanced:A snow skier is speeding down a mountain, going faster and fasterUnbalanced the skier is speeding up; acceleration requires unbalanced forcesA snow skier is being carried up the mountain by the lift. The lift moves at a constant speed.Balanced constant speed means no acceleration
