Activity! Create a small Domino house at your table. (10 Dominoes) –Use a straw to blow a ping pong ball and then a golf ball from one edge of the table toward the house with as much force as you can generate. –Make two inferences about your mission in your journal that deals with Force.

Follow-Up (Domino House)\

–The ping pong ball accelerated easily by blowing through the straw but bounced off of the domino house.

Follow-Up (Domino House)\ –The ping pong ball accelerated easily by blowing through the straw but bounced off of the domino house. –The golf ball required much more force (blowing through straw) but once moving caused more damage to the domino house.

Will the train be able to stop in time? Why? –Explain using Newton’s 2 nd Law. Copyright © 2010 Ryan P. Murphy

Answer! No! Trying to beat the train is a really bad idea. Copyright © 2010 Ryan P. Murphy

Answer! No! Trying to beat the train is a really bad idea. –The train can’t stop quickly because of its enormous mass and acceleration. The rails offer little friction. Copyright © 2010 Ryan P. Murphy

Video! Slip n’ Fly – –Disprove the validity of this stunt using Newtons Third Law

Answer: This stunt is fake because when he hits the pool the water goes up instead of in the opposite direction from the force.

Answer to Newton’s Cradle: Copyright © 2010 Ryan P. Murphy

Answer to Newton’s Cradle: Energy is dissipated in the form of heat, and friction. Copyright © 2010 Ryan P. Murphy

Answer to Newton’s Cradle: Energy is dissipated in the form of heat, and friction. The colliding balls, string, and the metal balls release heat. Copyright © 2010 Ryan P. Murphy

Answer to Newton’s Cradle: Energy is dissipated in the form of heat, and friction. The colliding balls, string, and the metal balls release heat. –The balls must push the air molecules aside which requires energy eventually slowing the process. Copyright © 2010 Ryan P. Murphy

Activity! Rollerblades or Skateboards and Newton’s 3 rd Law. –Students must wear helmets and have spotters nearby. –Stand tall on skateboard or roller blades (parallel) so forces can be clearly seen. –Students demonstrate the following. Push off of each other slowly. Pass a basketball back and fourth.
