Vectors and Projectiles

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. Learners ponder the given information and answer questions in the hopes of earning Stars and Medals. These Stars (for answering questions) and Medals (for completing levels or activities) are displayed on the screen, allowing a teacher to track student progress. The following Concept Builders target concepts associated with Vectors and Projectiles.

Vector Direction
Learning Goal:  To use a protractor to determine the direction of a vector and to express the direction using a couple of conventions and to convert direction information from one convention to another.

Vector Addition
Learning Goal:  To use an understanding of head-to-tail vector addition in order to determine the resultant of 3, 4, or 5 vectors.

Component Addition
Learning Goal:  To use the components of two or more vectors to determine the magnitude and diretion of their resultant.

Which One Doesn't Belong? Projectile Motion
Learning Goal:  To use an understanding of the characteristics of projectile motion in order to interpret various representations of a projectile's motion.

Trajectory - Horizontally Launched Projectiles
Learning Goal:  To demonstrate an understanding of the manner in which position and velocity change over the course of a projectile’s trajectory.

Trajectory - Angle Launched Projectiles
Learning Goal:  To understand the conceptual and numerical nature of the horizontal and vertical velocity vectors of an object that is launched upward at an angle to the ground.
