### Super Physics Facts

OK, so trying to figure out how things happen can be great fun for example Electricity is used and many different ways. Electricity exists in nature in many forms like lighting and electric eels have the ability to generate electricity within their body. Gravity keeps us on the ground so instead of us floating away when we jump in the air gravity is the ‘invisible force of nature’ that keeps us grounded. Energy exists all around us and there are a number of different types of energy that you will learn about in the Energy Facts section. So, let’s get started and we really hope you have fun.

• #### Wheel

The funny thing about wheels is that we are used to seeing them in use all around us but they are a manmade thing. There aren’t any wheels in nature and the only ones in the animal world that create and use them are human beings.

• #### Light

We see light from the sun every day. Light is measured in ‘waves’ and the light that we can see is only a small portion of the types of light. They are measured in the ‘electromagnetic spectrum’.

• #### Magnetism

Magnets and magnetic fields are part of the natural world. Playing with magnets are often the first introduction to science that kids experience. The earth is magnetic due to the fact that it contains rocks such as iron that are rich magnetic materials.

• #### Acceleration

Acceleration is a way that we measure how fast or the speed of something. Whether it’s a bike or a car, you know that when you press the gas pedal or start pedaling faster on your bike that you begin to increase your speed.

• #### Electricity

Many of the things you use in your home and at school uses electricity. We have come to not only rely on electricity, but expect that it is available whenever we need it.

• #### Mass and Weight

Mass and weight are two totally different things. Mass is the actual amount of matter that is contained in an object. Weight is the gravitational force that is pulling on an object.

• #### Energy

Energy exists all around us and there are a number of different types of energy. The food that we eat is broken down in our bodies and gives us the energy that we need to run, play and even think.

• #### Force

Whether you know it or not, you are surrounded by ‘forces’ every day. Force is just another word for the pull or push action that makes things move or in actuality to change the motion of an object due to the push or pull action.

• #### Friction

When you rub any two things together, this is called friction. It can be wiping a cloth across a table to wipe it clean or your boots as they skid along ice or snow.

• #### Momentum

Momentum is a term that describes the strength of a moving object. Objects that are not moving, do not have any momentum.

• #### Push and Pull

We are surrounded with forces everywhere we go and in almost everything that we do. Gravity is a force that keeps us on the earth. Friction is a force that heats things up.

• #### Gravity

Gravity is what we call an ‘invisible force of nature’, but in reality it exists throughout the universe. Gravity is one of the fundamental forces of nature along with: electromagnetism, weal nuclear forces and strong nuclear forces.

• #### Heat

We are all familiar with heat. We feel it on our face when the sun shines, we hear about the intense heat of a volcano and we know when we don’t have enough heat when it’s cold.

• #### Simple Machines

Simple machines allow us the ability to accomplish daily tasks easily. Many of these machines are things that you use and may not be aware of it.

• #### Sink and Float

We are all familiar with putting items in the water and watching them either sink to the bottom or float on top.

• #### Kinetic Facts

Anytime some is in motion it is said to have kinetic energy. This could be you when you are running down the street, a bicycle when it is moving or even the wind and water in the ocean.

• #### States of Matter

There are five ‘states of matter’ and each have different physical properties. If you look around you, you can probably identify at least three of them, because we live with them every day

• #### Temperature

Temperature is actually the speed of how fast or slow molecules and atoms of a substance are moving. We measure temperature through the use of a thermometer and use measurement scales based on Fahrenheit, Celsius and Kelvin.

• #### Laser

Laser light is not a natural form of light, but instead, has been manmade. We use lasers in so many things such as CD and DVD players, medical surgeries, bar code readers at the store, television and telephone signals carry laser light over special cables.

• #### Velocity

People often use the words velocity and speed as though they mean the same thing in how fast an object is moving. However, in the world of physics and science the two words don’t mean the same thing at all
