Elasticity & Hooke's Law - Intro to Young's Modulus, Stress & Strain, Elastic &

Elasticity & Hooke's Law - Intro to Young's Modulus, Stress & Strain, Elastic & Teacherflix 6 Views • 1 year ago

This physics video tutorial provides a basic introduction into elasticity and hooke's law. The basic idea behind hooke's law is that the change in length of a stretching or compressing an object is proportional to the force applied up to the proportional limit. The elastic limit is the point up to which an object can return to its natural state if the external force is removed. Beyond the elastic region lies the plastic region where an object will not return to its natural length if the external force is removed but it experiences permanent deformation. If the force passes the breaking point, the object will snap in two. The ultimate strength is maximum force that an object can withstand without breaking in two. Stress is the ratio of force and area. Stress is the external pressure applied to an object where as strain is the material's response to that stress. Strain is the ratio between the change in length of the object and its original length. The elastic modulus or young's modulus is the ratio between stress and strain. This video provides the equations and formulas needed to perform calculations associated with young's modulus /elastic modulus, stress, and strain.

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

Dinosaur Facts for Kids | Dinosaurs | Learn cool facts about the Age of Reptiles

Dinosaur Facts for Kids | Dinosaurs | Learn cool facts about the Age of Reptiles Teacherflix 16 Views • 1 year ago

What do you know about dinosaurs? In Dinosaur Facts for Kids, you will learn cool facts about many of these ancient animals. They lived during the Mesozoic era millions of years ago, which is divided into three smaller periods: Triassic, Jurassic, and Cretaceous. To this day, scientists still debate about the cause of their extinction. Was it because lots of volcanoes erupted at the same time? Or was it because a meteor crashed into Earth and caused a ton of damage?

Regardless, we can learn a lot about dinosaurs by studying their fossils. The first dinosaur bones ever found were found in China. The people originally thought they were the bones of giant dragons! The word dinosaur means “terrible lizard,” which works because most dinosaurs are classified as reptiles. Because of the work of paleontologists, we know that some dinosaurs walked on two legs while other walked on four. We also know that these terrible lizards varied greatly in size. Some were as small as chickens while others were bigger than a school bus!

The types of food that dinosaurs ate varied as well. Dinosaurs were either herbivores, carnivores, or omnivores, just like the animals of today. There are also some dinosaurs that are considered the ancient ancestors of birds!

We hope you and your student(s) enjoyed learning about these four different dinosaurs! If you want to learn even more, head over to our website and download one of our many free lesson plans about dinosaurs, full of activities, worksheets, and more!
