In this segment we define the terms momentum and impulse. We see the impulse-momentum theorem in action by analyzing the motion of a freerunner and the motion of an egg hitting two very different surfaces.
In this segment, we differentiate between elastic and inelastic collisions. The conservation of momentum and the conservation of energy are explored as we do examples involving these two types of collisions.
Work and energy are explored in this segment as we look at the work done by various types of forces. We also investigate what it means for the work done by an object when displacement and force are oriented in a variety of different ways.
We explain the work-energy theorem and solve an example problem involving the equations for work and kinetic energy. We also discuss when work has a positive or negative value.
We investigate Hooke's Law as we explore the concept of spring potential energy. We also examine how to find this energy mathematically and graphically.
We explore the inner workings of a hydroelectric dam as we learn about the law of conservation of energy. The difference between conservative and non-conservative forces is illustrated and we work through an example problem involving gravitational potential energy and kinetic energy.
We learn how power relates to electrical and mechanical systems. We explore the multiple ways we can express power mathematically by working through an example problem that ties in Newton's second law and kinematic equations to find its solution.
Your STEM students haven't been on a field trip in ages and they've had enough! They're taking extreme measures "to compare and contrast the characteristics, composition, and location of comets, asteroids, and meteoroids" by planning an interstellar field trip. Their rocket is almost ready, but they haven't started planning their spacesuits and you're a little worried that they don't fully understand the dangers of space travel. Join GPB Education and an intrepid potato for a STEMonstration about how meteoroids don't play nicely in space and what you can do to save the taternaut!
Host Raiany Silva takes students on a journey to feature sustainable infrastructures like the Atlanta Beltline, Clayton County Wetlands, and The Ray Highway in LaGrange. In order to understand the effects of human population growth on ecosystems, Raiany also visits Arabia Mountain High School to learn about sustainable design from teachers and students.
Located in Atlanta, the Centers for Disease Control and Prevention is probably the most recognized health institution in the world. It’s also one of Georgia’s biggest employers! Along with Teachable Moments about the CDC’s history, and definitions of epidemiology, mutation, and antibiotic resistance, we also learn that you don’t need a doctorate in biology to work here.
