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. 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.



Head-to-Tail Vector Addition
 
Learning Goal:  To identify the Head-to-Tail vector addition diagram that is consistent with a given vector addition equation.




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.




Free Fall
 
Learning Goal:  To express an understanding of the magnitude and direction of the velocity and acceleration vector for a free-falling object over the course of its trajectory.

Up and Down
 
Learning Goal:  To understand the conceptual and numerical nature of the velocity and acceleration vectors of an object that is launched vertically upward from the ground and travels through its full trajectory.

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.
