So, have you ever wondered why we have seasons? Or maybe where the sun goes when it's night time? *Hint: It doesn't actually go anywhere* In this episode of Crash Course Kids, Sabrina talks about the Earth's rotation and revolution and...

This video examines the force of gravity and looks at its critical role in the formation of the sun and planets of our solar system.

Discover how gravitational acceleration is calculated near Earth and why your weight changes with altitude, latitude, and Earth’s rotation. This lesson unpacks the physics behind g = a₉ − ω²R and shows how gravity subtly varies across...

Explore the intricacies of rocket stability and control. This part delves into the roles of rocket fins, the center of gravity, and the center of pressure, essential for maintaining a rocket's path and safety during...

Earth Science for Kids is the fun way to learn important facts about earth science and prepare for tests. Take a fascinating journey to the Super Science Station to learn about the solar system.

We know that gravity must cause clocks to run slow on the basis of logical consistency. And we know that gravity DOES cause clocks to run slow based on many brilliant experiments. But I never explained WHY or HOW gravity causes the flow...

Every year the moon’s orbit gets a little bigger and it moves just a little farther away. Should we worry about the Moon breaking free?

Physics Quiz. 5 Popular questions answered. Can you solve these questions?

Why do spaceships heat up when entering earth but not when exiting?, Why can I touch aluminum foil in the oven and not get burned?, Why are we able to see...

Scientists believe that the solar system took billions of years to develop! This video gives an overview of solar system basics - its beginnings, gravity, planets orbits.

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...

This video looks at moons: celestial objects that orbit planets. This video focuses on Earth’s moon: its formation, rotation, orbit, atmosphere, temperature, exploration, size, topography and how it effects life on Earth through the tides.

This video provides an overview of the Sun, explaining its role as a star and the largest object in our solar system. It discusses how the Sun formed, its layers, and its atmosphere. The video also includes review questions to reinforce...

Bill Paloski, former director of the Human Research Program at NASA’s Johnson Space Center, explores the idea of artificial gravity within a spacecraft for long-duration missions and explains how it may affect the human body from what we...

A cylindrical space station with a radius of 115 m is rotating at 0.292 rad/s. A ladder goes from the rim to the center. What is the magnitude of the centripetal acceleration at (1) the top of the ladder, (2) the middle of the ladder,...

Tidally locked planets could be more common than Earth-like planets! And these 'eyeball planets' might even be a promising place to look for unique lifeforms!

All the stars in a spiral galaxy rotate around a center -- but to astronomers, the speed that each star travels wasn't making sense. Why didn't stars slow down toward the edges as expected? Don Lincoln explains how a mysterious force...

We’ve created simulations to recreate the difference in time it takes for the Sun’s equator and poles to complete rotations, and the way we’ve solved is a bit surprising. And it looks like the Milky Way may not be great at mixing metals,...

How do plants grow in space? Can astronauts grow food in a zero-gravity environment? You can do your own experiments right here on Earth to find out! In this science project you will build your own device called a clinostat that rotates...

Satellite footage, telescopic photos and animation are used to teach students about the many fascinating aspects of our solar system. Viewers are introduced to ancient astronomers, telescopes, observatories and space exploration....

Dark Matter may be detected via Exoplanets. All the matter that is visible to us constitutes only about 18% of the total matter that we think actually exists in the universe. We know this because when all the known mass of...

There are many planets in the universe, but very few of them have qualities to support life Taking one celestial body at a time and determining whether it supports life would be slow and inefficient. So, astronomers look for certain...
