Presentation Transcript

  1. Forces & Motion Newton’s Laws of Motion

  2. Newton’s First Law • Vocabulary: • force • inertia • friction • speed • velocity • acceleration

  3. Newton’s First Law (Inertia) • Mass affects an object’s motion • Incline (slope) affects an object’s motion • Speed = position over time (airplane shadows) • Velocity = speed & direction (aircraft carrier and aircraft) • Acceleration = change in velocity • Acceleration = dependent on applied force & mass of an object

  4. Newton’s Second & Third Laws • Vocabulary: • balanced force • unbalanced force • action • reaction • work • simple machine • lever • fulcrum

  5. Newton’s Second & Third Laws • How do different forces affect an object’s motion? (Explore Activity- toy cars and rubber bands; KNEX- failing weight system, rubber band energy) • Balanced and Unbalanced forces = tug of war • Action/Reaction (3rd Law) = balloon rockets, rockets, rolly chair, cannon, canoe

  6. Simple Machines • Lever (pliers, teeter-toter, rake, etc.) • Pulley (flag pole) • Wheel & axle • Wedge (axe) • Inclined plane (ramps) • Screw

  7. KNEX • potential energy • kinetic energy • Falling weight system & gravity • Vehicle design
