Product Details

Two-in-one dynamics apparatus! Using the PSworks Photogate Timer, students record the transit times of a marble at different positions along the marble ramp. A convenient catcher at the bottom of the ramp stops the ball after each trial. A second experiment is performed by using the ramp as a projectile launcher. Students rotate the ramp so the curved end is at the edge of a tabletop. Engaging hands-on activities allow students to: • Calculate instantaneous speed • Determine acceleration • Explore conservation of energy • Investigate projectile motion • Compare experimental and theoretical values Precision-cut track is made of durable, high-quality wood. Complete instructions are provided. Flinn PSworks Support Stand and Photogate Timer are required and available separately.

Performance Expectations

HS-PS2-1: Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.
HS-PS2-2: Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system.
HS-PS3-1: Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
