I recall a NASA experiment from 1999 called the Newton Car [1] which actually can easily be adapted to age of PhyPhox!
Objective:
To investigate how increasing the mass of an object thrown from a Newton Car affects the car's acceleration over a rolling track (Newton's Second Law of Motion and conservation of momentum 'Impulserhaltung').
Description:
In this activity, students test a slingshot-like device that throws a mass causing the car to move in the opposite direction. Unlike in the original pre-smartphone instruction, we load the car with a smart phone running phyphox in acceleration measurement. Hence, we have the Newton car loaded with more mass!
Materials and Tools:
• 1 Wooden block about 10 x 20 x 2.5 cm
• 3 3-inch No. 10 wood screws (round head)
• 12 Round pencils or short lengths of similar dowel
• Plastic film canister - (ha ha, this will be a challenge ;-)
• Assorted materials for filling canister
(e.g. washers, nuts, etc.)
• 3 Rubber bands
• Cotton string
• Safety lighter
• Eye protection for each student
• Metric beam balance (Primer Balance)
• Vice
• Screwdriver
• Meter stick
• Smartphone, cell phone
