Learners review the fundamental laws of algebra including the commutative law of addition, the commutative law of multiplication, the associative law of addition, the associative law of multiplication, and the distributive law. Examples are given.

Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

In this interactive object, learners vary the value of the resistance to see how it affects current. Example problems are included.

Learners study animated rheostat settings that show how current flow is inversely proportional to resistance. Ten review questions complete the learning object.

Learners test their knowledge of the variations of Watt's Law and Ohm's Law with this quiz.

Learners study animated rheostat settings that show how varying the current flow affects the amount of power that is dissipated in a series circuit. Nine review questions complete the activity.

In this interactive object, students answer 10 questions covering Ohm's Law and Power Law.

Learners examine the relationship of voltage, current, and resistance as it applies to vehicle electrical systems.

Learners combine Boyle's Law and Charles's Law to solve for the pressure, volume, and temperature of a gas sample under two sets of conditions.

Boyle's Law states that gas volume varies inversely with the pressure at constant temperature and is described by the equation PV = constant. An example of a sample of gas at two conditions of P and V is used to illustrate the law.

The learner views several animations to study Newton's First Law of Motion, also known as "The Law of Inertia."

Learners apply the Law of Cosines to determine forces using a TI-36X calculator in this animated object.

In this interactive and animated object, learners apply the Law of Sines to determine forces using a TI-86 calculator.
