F = m × a lab
Engineers (Advanced), mission M1 Force, Mass & Motion, lesson 3 of 6.
Hook
Newton said force, mass and acceleration are linked. Can your data prove it?
Fair test
Two variables, one at a time: change force (0.5, 1, 1.5 N) at fixed mass, then mass at fixed force. Graph both.
Bonus challenge
Predict the time for a mystery mass before the teacher reveals it.
The build
Ballast Cart: A low cart with a tray for coins or washers and a hook for a spring scale or a falling weight. Change the mass, keep the pull: watch the speed change.
