Car Crash Lab

Define momentum momentum = mass X velocity

Materials: Gutter support Two gutters (one long, one short) Stop watch
Meter stick 6 toy cars Triple-beam balance

Roles Recorder Timer Car technician Meter stick tech.
Find mass of cars Release car (say go) Meter stick tech. Measure distance of ramp Measure distance of crashed car

Different Cars with different masses
Ramp Cars Measure in cm Same Car Every Time Crash Car

Different Cars with different masses
Ramp Car Measure in cm Same Car Every Time Crash Car

Different Cars with different masses
Ramp Cars Measure in cm Same Car Every Time Crash Car

Different Cars with different masses
Ramp Cars Measure in cm Same Car Every Time Crash Car

Different Cars with different masses
Ramp Cars Measure in cm Same Car Every Time Crash Car Which car had the most momentum? How do you know? The distance car traveled the furthest.

Hypothesis If I increase the mass of car 1 then the distance traveled by the crash car will (increase or decrease) because………….

Diagram/Procedures: Write on notebook paper or try to squeeze in the space.

Data Table: Time (sec) Distance of Crash Car Type of ramp car
Time (sec) Distance of Crash Car Type of ramp car Mass of ramp car Trial 1 Trial 2 Trial 3 Ave. time Ave. distance 1 2 3 4 5

Velocity of ramp car (distance of ramp car / time of ramp car)
Calculations: Velocity of ramp car (distance of ramp car / time of ramp car) Distance ramp car traveled (cm) (same every time) Ave Time of ramp car (s) Velocity (cm/s) 1 2 3 4 5

Find the momentum of ramp car 1-5, (p=m x v)
Calculations Cont. Find the momentum of ramp car 1-5, (p=m x v) Mass of Ramp Car (g) Velocity ramp car (cm/s) Momentum (g x cm/s) 1 2 3 4 5

Conclusions/Questions:
1. Fill in the following Chart, comparing the momentum of each ramp car with the distance that the crash car moved Momentum of ramp car (g x cm/s) Average distance crash car traveled (cm) 1 2 3 4 5
