Document Summary

Chapter 6 individual differences and motor abilities y people considerably vary skill performance due to many factors (body type, fitness level, attitudes/motivation, learning style, abilities). y people differ in many ways that influence their motor performance and learning. Scientists attempt to identify these individual differences that influence motor performance and learning. (not) testing individual differences. Differential approach y technique used when interested in learning about individual differences y. Individuals are the data points y retain information about individual differences y focuses on factors that make people different y. Individual performance on one test compared to performance on another test y only 1 group of subjects but at least 2 tests on each subject y does not infer causation y uses correlation techniques. Skills y ability stable enduring trait (primarily genetically determined) underlying skilled behavior. Inherited, genetic, innate, stable, enduring, unmodified by practice or experience. y skill capability developed as a result of practice (proficiency in performing a given task.

a) Evaluate the equivalent capacitance oftheconfiguration shown if all the capacitors are identical.

b) If a potential difference VAB isappliedbetween points A and B, what will be thepotentialdifferences across the individual capacitors in the top,middle andbottom rows?

(Answer: a) 11/6C b) Top: ÎVc = ÎVab; Middle: ÎVc =ÎVab/2; Bottom: ÎVc = ÎVab/3. )

Circuit 1 has 3 different light bulbs in a series.

In circuit I, the sequence of how bright the bulbs are goesfrom C, which is the brightest, to A, B is the dimmest.

1) In circuit I, rank the bulbs, from greatest to least, on thebasis of their potential differences. Explain fully.
2) In circuit I, rank the bulbs by the change in electric potentialenergy for an individual charge? Explain.
3) In circuit I, rank the bulbs by the greatest work done on anindividual charge by the electric field. Explain.

In circuit 2 all 3 bulbs are different. bulb C is in serieswith the battery, while bulb B is parallel to C and A is alsoparallel to both B & C.

4) Rank the bulbs in circuit II by brightness. Explain
