It explains the state of the system by state functions or state variables and describes internal energy as a state function.

This nugget explains mathematically how the net magnetic flux through any closed surface is zero.

This is a lecture video on Newton's second law and momentum, where the relationship between the change in momentum of an object and the resultant force acting on an object is explained. The video covers the derivation of the equation F =...

This video defines the difference between heat capcity and specific heat capacity. In this program students will learn why different substances heat up and cool down at different rates and come to understand how specific heat capacity of...

This example problem works shows that Velocity and Speed are different. It also illustrates that Speed is Not Velocity without direction.

This nugget explains about the heat energy,chemical energy and its types,electrical energy, nuclear energy and the equivalence of mass and energy.

How can we calculate the enthalpy change of a reaction without doing it? There are two easy ways! This is how we can make sure a reaction won't explode in our faces!

Linear equations can be used to solve many types of real-world problems. In this episode, the water depth of a pool is shown to be a linear function of time and an equation is developed to model its behavior. Unfortunately, ace Algebra...

Gravity and erosion are major factors in changing the shape of the surface of Earth. The different types of erosion, and the major types of mass movements caused by gravity are discussed in this video. Other terminology includes:...

Ionic Bond, Covalent Bond, James Bond, so many bonds! What dictates which kind of bond will form? Electronegativity values, of course. Let's go through each type and what they're all about.

Water on Earth focuses on water as most kids would think about it. We start with water in obvious locations such as oceans, lakes, and rivers. We quickly learn that water can change phase to remain a solid in glaciers. Many kids may be...

"Slope" is a fundamental concept in mathematics. Slope is often defined as "the rise over the run" ... but why?

Water on Earth focuses on water as most kids would think about it. We start with water in obvious locations such as oceans, lakes, and rivers. We quickly learn that water can change phase to remain a solid in glaciers. Many kids may be...
