Middle School Physics Momentum Lab: 3-page STEM packet on conservation of momentum, elastic collisions, kinetic compression waves, & percentage math.
Explore conservation of momentum, kinetic energy compression waves, and elastic collisions! The Newton’s Cradle Energy Transfer Challenge (FME03) challenges middle school student teams to act as physics research engineers, constructing a 5-sphere Newton’s Cradle apparatus to test linear momentum transfer and predictable collision dynamics.
Students explore conservation of energy, momentum conservation (p = mass x velocity), elastic vs. inelastic collisions, pendulum motion, V-suspension stability, and energy loss vectors!
