Island 2 Magnetic Marble Run
Mechanics and Structures
POP students will learn about different types of bridges and how they are engineered for strength. Then begin exploring virtual bridge design with Bridge Designer.
Island 2 Magnetic Marble Run
POP students are challenged to use the magnetic marble run to design and engineer tracks that can master the challenges.
INTRODUCTION:
Engineers are planners and problem solvers. They work to figure out the best way to build all kinds of things we rely on every day. Mechanical engineers, for example design things like engines, elevators, and the machines in factories. Civil engineers design roads, bridges, and airports. Electrical engineers design important components in everything from smartphones to satellites. All engineers use principles of physics (such as motion, force, gravity, and energy) in their work, just like you do when you build your marble run!
Newton’s First Law: An object at rest will remain at rest and an object in motion will remain in motion—unless some force acts upon it! INERTIA
Newton’s Second Law: Force is equal to mass time acceleration—that is, how fast and how far an object moves depends on how big it is and how hard you push it. F=ma
Newton’s Third Law: For every action, there is an equal and opposite reaction. EQUILIBRIUM.
