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?
You gain momentum.
m

2. Does the roller coaster ever get higher than the first hill? No
co
Explain. It would not have enough momentum to get higher than
eH w
the first hill.

ou urc
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,
aC s
Hill 2 = 0 cm, Hill 3 = 0 cm, 35-g car).

A. Press Play ( ) to roll the 35-gram toy car
down the track. Does the car break the egg? No

1. Click Reset ( ). Set Hill 1 to 80 cm, and click Play. Does the car break the egg? Yes
2. Click Reset. Lower Hill 1 back to 70 cm and select the 50-gram toy car. Click Play. Does

3. What factors seem to determine whether the car will break the egg?
The height of the hill and the weight of the care.

, Question: What factors determine the velocity 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, they are the
same.
2. Collect data: Find the final speed of a toy car in each situation. Leave the last column blank.
