Action-Reaction Forces AVID due 10/3 HONORS Due 10/2

Due Date:  Tuesday, October 2 for HONORS
Due Date  AVID: Wednesday, October 3 for AVID
Assignment: Use magazines, internet-images or drawings to create an illustration of action-reaction forces.
Materials Needed: plain white paper, scissors, glue or tape, markers

Examples:










Helpful Information:
Remember: When you jump, you push on the ground with your feet. This is the action force.  The ground pushes back on your feet with an equal and opposite force. This is the reaction force. You move upward from the jump because the ground is pushing you!



More Information: Action-reaction forces, though equal and opposite, do not cancel each other out because they act on different objects. Think about a volleyball player: when bumping the ball, the player esters an upward force on the ball. In return, the ball exerts an equal but opposite force on the wrist of the player. The action and reaction forces are acting on different objects (ball acts on wrist, wrist acts on ball)!



Compare and contrast the volleyball example above to this one: think about two volleyball players extorting equal and opposite forces on the ball. This would cancel out because both forces are being applied to the ball!  (hands act on ball and other hands act on ball)
