Product Details

Learn more about kinetic energy using these curving conservation of energy tracks! Will the track with the steep incline produce a ball with more kinetic energy than the straight track? Line up the catching curve at the bottom of one of the tracks, roll the ball down the track and mark the height it reaches on the catching curve. Repeat this for all four tracks. Students will easily see a similarity—all four marks on the catching curve are at the same height! This activity quickly illustrates that the kinetic energy of a ball at the bottom of a track is directly related to the potential energy it had at the top. When a ball drops a certain distance, it will always have the same kinetic energy no matter what path it took to get to the bottom. An exciting test of the conservation of energy principle! Precision-cut tracks are made of durable, high-quality wood. Complete instructions are provided.

A Flinn PSWorks™ Support Stand or other support stand and clamp is required, but not included.

Performance Expectations

MS-PS3-1: Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object.
MS-PS2-2: Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object
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.
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-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.
