Gravity explained for kids is not altogether different from gravity explained to grown-ups. It is a strange concept, best explained by noting the difference between mass and weight, and how gravity can only act on objects with mass (which excludes photons and therefore visible light).
in improving the differential movement between various particles during gravity separation and eventually sorting different particles [2]. When water is removed, and air plays the role of separation medium, the separation method is defined as dry, pneumatic, or air gravity separation [3]. In general, dry gravity separation has
Let's start at the beginning. If you drop a stone, it falls to the floor. Why is this? Everyone knows that the answer is 'Gravity'! But what is gravity? It's more than just a word! The real answer is that a force – a force we call gravity – is acting on the stone, and pulling it towards the Earth. Gravity …

Gravity is the force that pulls everything in the Earth's orbit toward it. Learn more about the definition, law, and facts about gravity and its place in the universe.
Our Falcon Concentrators use the science of gravity separation to recover minerals. But what is the science driving this process?
Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension.The layer closer to the top of the container—the less dense of the two liquids, or the liquid from which the precipitate or sediment has settled out—is poured off, leaving the other component or the more dense …
Do you know what is gravity?. Gravity is one of the fundamental forces. Learn about the history, laws, and examples of gravity.
Terminal Velocity. The key variable in gravity separation calculations is the terminal velocity of the settling particle. The terminal velocity indicates whether a heavy particle will separate against an upward fluid flow or whether a system has sufficient residence time for a particle to settle.
Gravity is what keeps our feet on the ground. Our center of gravity keeps us, and other objects, from falling over. In this lesson, we will learn...
Student Dictionary for Kids Search an online dictionary written specifically for young students. Kid-friendly meanings from the reference experts at Merriam-Webster help students build and master vocabulary.
Learn that gravity is a force that pulls things down. It doesn't matter how heavy it is or if you throw it, gravity pulls it to Earth's surface. Watch now!
Gravity is a pulling force that works across space. That is, objects do not have to touch each other for the force of gravity to affect them. For example, the Sun, which is millions …
Kids learn about separating mixtures in chemistry including separation processes such as filtration, distillation, and the centrifuge.
Learn Specific gravity facts for kids. Specific Gravity (SG) is a special case of relative density.. It is defined as the ratio of the density of a given substance, to the density of water (H 2 O). Substances with a specific gravity greater than 1 are heavier than water, and those with a specific gravity of less than 1 are lighter than water.
Why do things fall to the ground when you let go of them? It's all to do with gravity! Learn about what gravity is with a simple definition and everyday examples of …
Facts About Gravity | Understand important concepts, their definition, examples and applications. Also, learn about other related terms while solving questions and prepare yourself for upcoming examination.
The special theory of relativity describes systems where gravity is not an issue; by contrast, gravity is the central issue of the general theory of relativity. In general relativity there is no gravitational force deflecting objects from their natural, straight paths. Instead, gravity is seen as changes in the properties of space and time.

gravity separation A concentration process based on differences in specific gravity between ore and gangue minerals. Source for information on gravity separation: A Dictionary of Earth Sciences dictionary.
We have written this article on Friction and Gravity for kids to introduce children to these forces and explain how they work.
Jigging separation is the gravity concentration process that realizes layering and separation based on the motional differences of particles in the alternate motion direction of the medium.
Gravity separation of suspended material from water is the oldest and most widely used process in water treatment. Particle settling is dependent on the nature of the particle and geometry of the sed...
What is meant by 'decanting' in chemistry? Decantation is a process used to separate mixtures of liquids and solids or two immiscible liquids.
Gravity is a force which pulls things towards the centre of Earth. It was discovered by Sir Isaac Newton. Find out more in this Bitesize primary KS2 science guide.
