Analyzing a Direct Measurement Video of a Ballistic Pendulum
Conditions of Use:
Remix and Share
Rating

Ballistic Pendulum is an activity that utilizes the Law of Conservation of Energy and the Law of Conservation of Momentum to determine the velocity of a Peanut M&M that is shot from a cannon into a cup. The activity walks students through the problem step by step to get the outcome, asking conceptual and math problems along the way to obtain the final product: the velocity of the Peanut M&M.

Conservation of Linear and Angular Momentum During a Collision
Conditions of Use:
Remix and Share
Rating

This activity is intended as an introduction to the concept of the angular momentum of a particle moving in a straight line. Students will use a video of a marble colliding with a wood block to analyze how both linear and angular momentum are conserved during a collision. Students will use a QuickTime video recorded at 960 frames per second, making measurements directly from the video using rulers and a frame-counter overlaid on the video. The video at right is a preview of the video students use for the activity.

Direct Measurement Video of a Bouncing Ball
Conditions of Use:
Remix and Share
Rating

This is an activity presents an opportunity for students to practice problem solving using a direct measurement video. The video shows an inflatable rubber ball bouncing across a stage. Students make measurements from the video and calculate the velocity for the ball just as it completes the first bounce and leaves the floor on the way up. Students will use a QuickTime video recorded at 120 frames per second, making measurements directly from the video using one given dimension and a frame-counter overlaid on the video. The video at right is a preview of the video students use for the activity.

Direct Measurement Video of a Toy Car Accelerating
Conditions of Use:
Remix and Share
Rating

This is a short activity intended to allow students to practice kinematics using a video of a familiar object: a spring-powered toy car. Students measure displacement and elapsed time from the video and use these measurements to calculate average speed. Observing that the car has an initial speed of zero, students can find the final speed and acceleration. Students will use a QuickTime video recorded at 240 frames per second, making measurements directly from the video using a ruler and a frame-counter overlaid on the video. The video at right is a preview of the video students use for the activity.

Lab: Horizontally Launched Projectiles (with uncertainty analysis)
Conditions of Use:
Read the Fine Print
Rating

This is a version of the time-tested lab where students roll a ball off a table top and use kinematics in two dimensions to try to predict where the ball will land. While many versions of this lab have been previously published, in this version students determine the uncertainty of all measurements and uncertainty of their prediction. The techniques and vocabulary are consistent with the Introduction to Measurement packet.

Lab: Measuring the Speed of Sound in Air (with uncertainty analysis)
Conditions of Use:
Read the Fine Print
Rating

Students use a microphone and Vernier LabQuest to record the sound of a finger-snap echo in a 1-2 meter cardboard tube. Students measure the time for the echo to return to the microphone, and measure the length of the tube. Using their measurements, students determine the speed of sound. While other authors have produced similar labs, this version includes uncertainty analysis consistent with effective measurement technique as presented in the module Measurement and Uncertainty.
