This video discusses the principle of force and the application of Newton's Three Laws of Motion. Students will witness the effect of friction on force and see how force is calculated. Other terminology includes: inertia, weight, mass,...

The video explains a required physics practical activity that investigates the relationship between the acceleration of an object and its mass, keeping the force constant. The experiment uses a trolley being accelerated by the weight of...

This video provides an overview of non-contact forces, such as gravitational, electric, and magnetic forces, explaining how they act at a distance without physical contact between objects. It covers the concepts of force magnitude,...

What are the differences between solids, liquids, and gases? In this program students will investigate real-life examples of the various phases of matter. Colorful animations illustrate how these states differ in the movement of...

Yesterday's election results have a lot of impact on health care in the United States. The new Democratic House of Representatives and the ACA, expansion of Medicaid in red states, and medical and recreational marijuana are all affected...

Every company starts somewhere, even Apple and Google were once just tiny startups! No one knows what the future holds, but these 10 businesses could be topping the global ladder in a decade's time - and changing the world while they're...

Many organic chemistry students think that specificity and selectivity are essentially synonymous when describing the potential products of a chemical reaction. But this is not true! They have separate meanings and imply different...

This video provides a description of the properties and characteristics of water. It explains that water can exist as a solid (ice), liquid, or gas (steam), and is the only naturally occurring compound that can do so. The video also...

There are many, many factors that contribute to high drug prices. Regulating them is complicated. It turns out, expensive drugs are often expensive because they're hard to replicate. We try to shed some light on the situation.

In this lesson, your instructor discusses vectors. This clip is from the chapter "Input, Process and Output" of the series "C++ for Beginners".null
