Activity 5: Tug of WarReview terms:
Evidence of a Force: - A change in motion 1. A stationary object starts to move 2. A moving object starts to speed up 3. A moving object starts to slow down or stop 4. A moving object changes directions Net Force: - Combination of all forces acting on an object Balanced forces: - When the net force on an object is zero. - Balanced forces don't cause a change in motion Unbalanced forces: - When the net force of an object is greater than zero - Unbalanced forces cause a change in motion Watch: "Tug of War" movie clip Assignment: After watching the "Tug of War" movie clip, explain how the game of Tug of War demonstrates balanced and unbalnced forces. |
