### 1-Dimensional Kinematics

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 in 1-Dimensional Kinematics.

Distance vs. Displacement

Learning Goal:  To analyze a multi-stage motion and to determine the distance and the displacement for that motion.

Matching Pairs: Speed-Distance-Time
Learning Goal:  To use the average speed, distance, time relationship to relate quantitative information to one another.

Acceleration
Learning Goal:  To identify whether an object accelerates or not, to determine the direction of the acceleration, and to determine the acceleration value if given simple numerical data.

Name That Motion
Learning Goal:  To use an understanding of the language of kinematics in order to accurately match an animation of a motion to the corresponding verbal description of that motion.

Motion Diagrams
Learning Goal:  To construct the motion diagram for a given motion, showing properly-spaced dots, velocity vectors, and acceleration vectors.

Graph That Motion
Learning Goal:  To use an understanding of the principles of kinematic graphing in order to accurately match an animation of a motion to the corresponding position-time graph or velocity-time graph of that motion.

Match That Graph
Learning Goal:  To analyze the position-time graph for an object's motion and to match it to the corresponding velocity-time graph ... or vice versa.

Position-Time Graphs - Conceptual Analysis
Learning Goal:  To analyze a position-time graph and associate the graph features with motion characteristics of a moving object.

Position-Time Graphs - Numerical Analysis
Learning Goal:  To analyze a position-time graph in order to determine the object’s disance traveled, displacement, and velocity.

Velocity-Time Graphs
Learning Goal:  To relate a verbal description of an object’s motion to the corresponding velocity-time graph representing the motion.

Dots and Graphs

Learning Goal:  To analyze a dot diagram and match the motion that it describes to the appropriate position-time or velocity-time graph.​

Words and Graphs

Learning Goal:  To identify the velocity-time graph that matches the verbal description given for an object’s motion.

Which One Doesn't Belong?

Learning Goal:  To interpret various representations of an object’s motion in order to identify which representation is not like the others.

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.
