Name: Mia Calcagno Date: 2-1-2021 Student Exploration: Roller Coaster Physics 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? The car is pulled up a long hill. 2. Does the roller coaster ever get higher than the first hill? No Explain. The roller coaster cannot go higher than the first hill because the total energy of the roller coaster cannot increase and some was wasted in heat with friction. 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). 1. Press Play ( ) to roll the 35-gram toy car down the track. Does the car break the egg? No 2. Click Reset ( ). Set Hill 1 to 80 cm, and click Play . Does the car break the egg? Yes 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? The mass of the car and the speed of the car. 4. What factors seem to determine whether the car will break the egg?
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.) A. Click Play . What is the final speed of the toy car? 442.9 cm/s B. Try the other cars. Does the mass of the car affect its final speed? No 2. Collect data: Find the final speed of a toy car in each situation. Leave the last column blank.
