Experiment 2

Pre-lab section:

1) Introduction: Explain the theory behind this experiment in a paragraph between 150 and 250 words. (2 Points)

Suppose you are using external resources; include the reference. It would be best if you had any relevant formulas and explanations of each term. You may use the rich formula tools embedded here.

2) Hypothesis: In an If /Then statement, highlight the purpose of the experiment.

For instance: If two same shape objects with different masses are dropped from the same height, they will hit the ground simultaneously. (2 points)

Post-lab section:

1) Introduction (≈180 words)

This experiment investigates the relationship between [identify independent variable] and [identify dependent variable] to test how changes in one affect the other under controlled conditions. The theoretical basis is that [state the relevant law or principle — e.g., Newton’s second law, Hooke’s law, conservation of energy, Ohm’s law, diffusion kinetics, etc.], which predicts that when [independent variable] changes, [dependent variable] will [increase/decrease/behave in X way] according to a mathematical relationship. For example, if studying a spring-mass system, Hooke’s law (F = −k x) and the equation for simple harmonic motion (T = 2π√(m/k)) relate force, displacement, mass, spring constant, and period. In the procedure we measure [dependent variable] at several controlled levels of [independent variable], keeping other factors constant (temperature, friction, initial conditions) to isolate the effect. Data will be analyzed using graphical methods (best-fit line or curve), calculation of percent error versus theoretical predictions, and discussion of sources of experimental uncertainty. The experiment tests whether observed behavior matches theoretical expectation and provides practice in measurement, data analysis, and error estimation.
