In this video we are teaching about the types of organisations that is sole proprietor, partnership firm, joint stock company, also the comaparison and summary of the organisations.

According to NASA, the mass of the Earth is 5.97 x 10^24 kg, the mass of the Moon is 7.3 x 10^22 kg, and the mean distance between the Earth and the Moon is 3.84 x 10^8 m. What is the force of gravitational attraction between the Earth...

In this video you will about weight, force, mass and gravity. When it says 56 kilograms on your bathroom scales, what are you actually measuring? Well, if you said weight, like most people would, then you are sort-of wrong! Kilograms are...

Snakes don’t have lips, they can't lap up water, and they don’t grab mouthfuls of water and tip their heads back to swallow, so how do they drink? Turns out, some snakes have sponge-mouths that literally soak up water!

How the Moon affects daily tides and drives extreme spring tides, when the Sun and Moon align. Physics - Our Solar System - Learning Points. The Moon creates and controls the tides. Its gravitational pull causes ocean water to bulge...

Kenny Harris, a NASA engineer named to Forbes' 30 Under 30 Class of 2020, discusses his experiences as a young professional.

The Moon holds Earth in place and dictates our seasons. What happens to planets without a moon like ours? Physics - Our Solar System - Learning Points. The Moon formed after Earth collided with its twin, Theia. In proportion to the size...

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,...

This program begins by discussing common ways mass and volume are measured in the home. The video highlights how mass and volume are measured with various types of equipment in the school science lab. Some of the different tools used to...

In this video Paul Andersen explains how an object with mass placed in a gravitational field experiences a gravitational force. On the Earth this gravitational force is known as weight. The gravitational force is equal to the product...

NASA has been using swimming pools to train astronauts since the 1960s. The largest is the Neutral Buoyancy Laboratory (NBL), which holds roughly 9 olympic pools worth of water and has contained not just mockups of space station and...

Finally, after what seems like eons and eons, the end is nigh. We're talking not only about the end of Crash Course Big History, but also the end of everything. The end of humanity and the end of the universe.John and Hank Green will...

This video provides a clear explanation of tides, describing how they are caused by the gravitational pull of the moon and the sun. It explains the different types of tides, including high tides, low tides, spring tides, and neap tides....
