In this animated object, learners follow the steps for solving word problems using algebra. An introductory example is explained.

In this interactive learning object, students calculate a resultant of multiple forces acting in a concurrent, coplanar condition.

In this animated object, learners use an algebraic formula to solve the following problem: An airplane travels a certain distance with the wind in the same amount of time that it takes to travel a shorter distance against the wind. Given a constant wind speed, what is the speed of the plane without a wind?

In this learning activity you'll practice calculating a combined variation problem.
