WebThe relationship between acceleration and mass Repeat steps 1 to 8, but this time apply the same force in all cases. Vary the mass by stacking up to three trolleys. (Two cords in parallel helps when pulling more trolleys.) For simplicity, you can use a trolley mass as a unit of mass (instead of mass in kilograms). Teaching Notes WebA more descriptive name would be coefficient of linear correlation. The following example shows that all probability mass may be on a curve, so that Y = g(X) (i.e., the value of Y is completely determined by the value of X ), yet ρ = 0. Example 12.2.5 Y = g(X) but ρ = 0 Suppose X ~ uniform (-1, 1), so that fX(t) = 1 / 2, − 1 < t < 1 and E[X] = 0.
