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.
A trip to any mall will give you a look at thousands of items that weren’t created down the street. Many of them were imported from distant lands. And the Georgia Ports Authority in Savannah … the fourth largest port in the country … is the point of entry for, quite literally, tons of them. The Georgia Ports Authority has a job for just about any interest. They’re governed by logistics and driven by technology—technology that you might be able to learn by … playing video games. You’ll want to see this.
Directly addressing modern social issues that students care about can stimulate provocative conversations about the roles of research and science in society. With more than 400 STEM resources from collections like Above the Noise, It’s Okay to be Smart, Braincraft, and the Origin of Everything, participants will learn to navigate the most engaging content in the PBS universe while connecting standards from the classroom with the world beyond.
Who says physics can’t be fun? They can be very entertaining when you use them to go zip lining. And that’s what we do at North Georgia Canopy Tours in Lula. Of course, we go zip lining with a focus on physics and environmental education. That means getting employees to explain how Sir Isaac Newton’s basic laws influence their jobs. Teachable Moments include explanations of Newton's First Law of Motion, friction, and watersheds.
