.The Roller Coaster Physics Gizmo models a roller coaster with a toy car on a track that leads to You can change the track or the car. For experiment, use the default settings (Hill 1 = Hill 2 = o cm, Hill 3 = o cm, 1. Press Play ( ) to roll the 35-gram toy the track.

\\\ G 2. Click Reset ( ? ). Set Hill 1 to 80 cm, and click Play. Does the car break the egg? t 3. Click Reset. Lower Hill 1 back to 70 cm and select the 50-gram toy car. Click the 50-gram car break the Play. Does egg?
Activity A: Get the Gizmo ready: Roner coaster Click Reset. I~ speed Select the 35-g toy car. Question: What factors determine the speed of a roller coaster? 1. Observe: Set Hill 1 to 100 cm, Hill 2 too cm, and Hill 3 too cm. Be sure the friction is set to 0.00. (This means that there is no friction, or resistance to motion.) ---Coefficient of
