Student Exploration: Roller Coaster Physics Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary : friction, gravitational potential energy, kinetic energy, momentum Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Sally gets onto the roller coaster car, a bit nervous already. Her heart beats faster as the car slowly goes up the first long, steep hill. 1. What happens at the beginning of every roller coaster ride? Name: Lezlie Pena Date: 02-24-21
2. Does the roller coaster ever get higher than the first hill? Explain.
Gizmo Warm-up The Roller Coaster Physics Gizmo models a roller coaster with a toy car on a track that leads to an egg. You can change the track or the car. For the first experiment, use the default settings ( Hill 1 = 70 cm, Hill 2 = 0 cm, Hill 3 = 0 cm, 35-g car). Press Play ( ) to roll the 35-gram toy car down the track. Does the car break the egg? 2. Click Reset ( ). Set Hill 1 to 80 cm, and click Play . Does the car break the egg? 3. Click Reset . Lower Hill 1 back to 70 cm and select the 50-gram toy car. Click Play Does the 50-gram car break the egg? 4. What factors seem to determine whether the car will break the egg? 1. Press Play ( ) to roll the 35-gram toy car down the track. Does the car break the egg? 2. Click Reset ( ). Set Hill 1 to 80 cm, and click Play . Does the car break the egg? 3. Click Reset . Lower Hill 1 back to 70 cm and select the 50-gram toy car. Click Play Does the 50-gram car break the egg? no yes .
Question: What factors determine the speed of a roller coaster? 1. Observe: Set Hill 1 to 100 cm, Hill 2 to 0 cm, and Hill 3 to 0 cm. Be sure the Coefficient of friction is set to 0.00. (This means that there is no friction , or resistance to motion.) 2. Collect data: Find the final speed of a toy car in each situation. Leave the last column blank.
