Below are sample questions representative of the exercises included on this worksheet and related 6.49 Newton's Third Law and Collision Safety Design skill assessments:

Problem 1Difficulty: Mastery

Which procedure best controls variables for validation?

ARun the simulation and experiment with different masses and speeds and compare whether both look like a crash.

BCrashed the real cart once and decide the simulation is correct if it seems close.

CAdjust simulation settings until it matches one experimental trial, without measuring the real material properties.

DMatch initial conditions exactly: same cart mass, same impact speed, same crumple-zone geometry/material properties (as measured), and same boundary conditions (barrier stiffness); then compare force–time curves and deformation between simulation and experiment.

Solution & Explanation:Validation requires matching initial and boundary conditions. Measuring and matching mass, speed, geometry, and barrier stiffness controls variables so differences reveal model accuracy.

Problem 2Difficulty: Mastery

Which procedure best controls variables and uses a robust comparison metric?

AUse only the single highest recorded force value from one trial.

BChange filtering settings for each bumper to make the graphs look clean.

CUse controlled repeated trials, and compare the average impulse (area under force–time curve) or the average peak force computed after smoothing/consistent filtering applied equally to both designs.

DCompare bumpers by how they feel when you squeeze them.

Solution & Explanation:Controlling trials and using impulse or consistently processed peak force reduces sensitivity to single noisy points, improving fairness and reliability.

Problem 3Difficulty: Mastery

Which procedure best controls variables to prevent degradation from biasing the comparison?

ATest the old material first for all trials, then test the new material.

BAlternate or randomize the order of material tests, use fresh samples (or track impact count and replace at the same schedule), keep speed and mass constant, and compare averages for equal numbers of impacts.

CCrashed the new material at higher speed because it is stronger.

DUse a different sensor each time to avoid wear.

Solution & Explanation:Randomizing/alternating order and using fresh or equally aged samples controls material degradation as a confounding variable.
