The reason airplane flights take longer when traveling west is because of the different speeds of rotation on Earth. The rotational velocity of Earth decreases as one goes from the Equator to the poles. This means that a place on the...

Carrying a pole helps the walker increase their rotational inertia, which aids in maintaining stability while walking over the narrow rope. The pole also adds more weight below the center of gravity of the walker, which is another bonus...

An increase in Earths rotational speed could have various impacts on life: ranging from increased earthquakes and tsunamis to a shortening of the length of the day. People could be floating in central Africa while the polar ice might...

Orbital poles are the two regions of a planet at the extremes of its rotational axis.

Discover how parallax can be used to measure distances, and how early astronomers used it to find the distance of stars from Earth. Maths - Space A Twig Math Film. Reinforce and extend the learning required by the curriculum. Twig’s math...

What are central forces and how do they make objects spin or turn? Physics - Forces - Learning Points. A centripetal force makes an object follow a circular path. The moment of inertia is the resistance of an object when the speed of...

Our sky is split into 88 different sections called constellations, which have been recognised and used by humans for centuries. Physics - Our Solar System - Learning Points. Constellations are set patterns of stars, such as Ursa Major....

What is the difference between day and night? How is this governed by the Earth's movement? Physics - Our Solar System - Learning Points. The Sun generates light. The Earth spins on its axis. A full rotation of Earth takes 24 hours. The...

Unreachable by man, scientists have developed a complex experiment to demonstrate the heat and pressure at the centre of the Earth. Earth Science - Geology - Learning Points. The Earth's core is a dense ball of iron and nickel. To...

What makes a tornado nature's most dangerous storm? Scientists are working to identify the unique set of circumstances which combine to create a tornado. Earth Science - Weather - Learning Points. Tornadoes are a violent, spinning vortex...

To survive, plants have developed adaptations to regulate temperature and water, and maximise the capture of sunlight. Some plants have even evolved to survive in extreme environments of hot deserts and Polar regions. Biology - Plants -...

The weather systems on our planet are all driven by one thing: air. Discover how our weather is driven by energy from the Sun, affecting the movement of air. Earth Science - Weather - Learning Points. Our weather is a chaotic and complex...

What is the Coriolis effect? How is it produced and how does it affect our weather? Earth Science - Weather - Learning Points. The way wind blows determines thunderstorms to hurricanes. The Coriolis Effect is a deflection of moving mass...

Explore the reasons why objects can keep moving on their own, and why most of them will eventually stop. Physics - Forces - Learning Points. Momentum is how we quantify a moving object. Outside forces affect momentum. Momentum is...

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...
