1) Which type of inertia describes a passenger moving forward when a fast-moving car suddenly hits the brakes? a) Inertia of Rest b) Inertia of Gravity c) Inertia of Direction d) Inertia of Motion 2) You have two identical plastic bottles: one is empty and the other is filled with water. Which statement is TRUE regarding their inertia? a) the empty bottle has more inertia because it is lighter b) both have the same inertia because they are the same size c) the bottle filled with water has more inertia because it has more mass d) Neither bottle has inertia because they are not moving yet. 3) n the "Tablecloth Challenge" (Station 3), why does a heavy beaker of water stay on the table when the paper is pulled away quickly? a) Friction pushes the bottle backward. b) the bottle's inertia of rest resists the change in motion c) the bottle's inertia of motion pulls it forward d) gravity disappears for a split second 4) According to your observations in "The Surface Struggle" (Station 4), why does a toy car stop much sooner on sandpaper than on a smooth floor? a) sandpaper has more mass than the car b) sandpaper provides a stronger force of friction that opposes motion c) the car gains more inertia when it touches the sandpaper d) smooth floors have no inertia 5) Which of the following would be the HARDEST to stop once it is moving at 5 km/h? a) rolling marble b) moving bicycle c) rolling toy car d) moving truck
