Source: Nicholas Timmons, Asantha Cooray, PhD, Department of Physics & Astronomy, School of Physical Sciences, University of California, Irvine, CA The goal of this experiment is to understand the components of force and their relation to motion through the use of Newton's second law by measuring the acceleration of a glider being acted upon by a force. Nearly every aspect of motion in everyday life can be described using Isaac Newton's three laws of motion. They describe how objects in...

Introduction to Test of Independence

In statistics, the term independence means that one can directly obtain the probability of any event involving both variables by multiplying their individual probabilities. Tests of independence are chi-square tests involving the use of a contingency table of observed (data) values. The test statistic for a test of independence is similar to that of a goodness-of-fit test: where: O = observed values E = expected values (which should be at least 5) A test of independence determines whether...

Hypothesis Test for Test of Independence

The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are: H0: The two variables (factors)...

Source: Laboratory of Jeff Salacup - University of Massachusetts Amherst The distribution of a group of organic biomarkers called glycerol-dialkyl glycerol-tetraethers (GDGTs), produced by a suite of archaea and bacteria, were found in modern sediments to change in a predictable manner in response to air or water temperature1,2. Therefore, the distribution of these biomarkers in a sequence of sediments of known age can be used to reconstruct the evolution of air and/or water temperature on...

Manipulating an Independent Variable through Embodiment

Source: Laboratories of Gary Lewandowski, Dave Strohmetz, and Natalie Ciarocco—Monmouth University In any experiment, the researcher attempts to manipulate participants in one group to have different thoughts, experiences, or feelings than the other groups in the study. Some manipulations are overt, while others can be quite subtle. Embodiment is a growing research area focused on the theory that subtle physical experiences can unconsciously influence a person’s thoughts. For example if a...

Under the same gravitational conditions, gravitational force scales with an object's mass. Newton's second law then computes acceleration by dividing that force by mass, so the mass factor cancels. The resulting acceleration depends on field conditions rather than the object's mass, provided air resistance is negligible. This cancellation is the central mathematical mechanism.
When air resistance is negligible, gravitational force and mass cancel through Newton’s second law. If air resistance becomes significant, the motion is no longer governed by gravity alone, so objects may not display the ideal mass-independent result. This condition is why tests and analyses must account for whether surrounding effects permit the approximation.
Mass Independent Acceleration provides a way to compare how bodies move in the same gravitational conditions without making their masses the deciding factor. Such comparisons form a foundation for testing the equivalence principle. The principle therefore links Newtonian motion analysis with precision investigations of whether gravitational behavior is consistent across bodies.
In projectile motion, the gravitational part of the acceleration can be treated as common to objects in the same uniform field, rather than assigned separately according to mass. This lets analysis focus on motion produced by the field and supports comparisons among projectiles while retaining the condition that air resistance is negligible.
Orbiting bodies are another setting in which gravitational acceleration is central. Because the acceleration is tied to the gravitational field rather than to the body's mass, Mass Independent Acceleration helps explain why orbital motion can be analyzed through the field acting on the body. The same reasoning extends the free-fall principle beyond objects moving straight downward.
A precision test can compare the accelerations of bodies with different masses while placing them under the same gravitational conditions. The analysis should treat air resistance as negligible or recognize it as a limitation. If measured accelerations agree, the result supports the mass-independent gravitational model and contributes to tests of the equivalence principle and gravitational fields.
