Forces in 2-Dimensions
A Concept-Builder is an interactive questioning module that presents learners with carefully crafted questions that target various aspects of a concept. Each Concept Builder focuses the learner's attention upon a discrete learning outcome. Questions target that outcome from a variety of angles using multiple difficulty levels or varying activities. The following Concept Builders target concepts associated with Forces in Two Dimensions.
Solve It! (with Fnet = m•a and Vectors)
Learning Goal: To use vector resolution and the Fnet = m•a equation to analyze situations involving a horizontal acceleration caused by a force applied at an angle to the horizontal.
Equilibrium
Learning Goal: To use concepts of equilibrium and vector components in order to add two forces to an object so as to establish an equilibrium state.
Free-Body Diagrams for Inclined Planes
Learning Goal: To construct a free-body diagram for both a basic and a complex inclined plane situation.
Solve It! - Inclined Planes
Learning Goal: To use vector principles and Newton’s laws to analyze situations involving objects moving along inclined planes.
