Light is a form of electromagnetic radiation that is visible to the human eye.]]> 2023-02-02 19:10:46 UTC https://padlet.com/392284/4ih53lg67ygr7auk/wish/2466645444 392284 https://padlet.com/392284/4ih53lg67ygr7auk/wish/2466645764 Electrical energy is energy carried by charged particles. It is also known as moving electrons.]]> 2023-02-02 19:10:59 UTC https://padlet.com/392284/4ih53lg67ygr7auk/wish/2466645764 392284 https://padlet.com/392284/4ih53lg67ygr7auk/wish/2466646013 Sound energy is energy is carried by sound waves. Sound energy is created when something vibrates.]]> 2023-02-02 19:11:11 UTC https://padlet.com/392284/4ih53lg67ygr7auk/wish/2466646013 392284 https://padlet.com/392284/4ih53lg67ygr7auk/wish/2466646574 Thermal energy is energy associated with temperature. The hotter something is, the more thermal energy it has.]]> 2023-02-02 19:11:34 UTC https://padlet.com/392284/4ih53lg67ygr7auk/wish/2466646574 392284 https://padlet.com/392284/4ih53lg67ygr7auk/wish/2466646738 Chemical energy is energy stored within the bonds of atoms of matter. It is used to keep atoms bonded together.]]> 2023-02-02 19:11:41 UTC https://padlet.com/392284/4ih53lg67ygr7auk/wish/2466646738 392284 https://padlet.com/392284/4ih53lg67ygr7auk/wish/2485455185 Energy can change. This is called energy transformation. An example of this is riding a bike. First your legs move which is mechanical energy, then the wheels that are moving rub against the ground, creating sound energy. Another example of this is bouncing a basketball. The mechanical energy of the moving ball hits the floor, so the mechanical energy changes into sound energy.]]> 2023-02-16 19:06:21 UTC https://padlet.com/392284/4ih53lg67ygr7auk/wish/2485455185 8421101 https://padlet.com/392284/4ih53lg67ygr7auk/wish/2485460270 An object can transfer more than one type of energy. This is because a flame, for example, can transfer both heat and light energy. This heat, which is obvious because it's a campfire, is very large and immense. There is also lots of light, or radiant energy, being released. Another example is riding a bike. As you push the pedals, the bike moves, which transfers to mechanical energy but also sound energy from the bike actually moving.]]> 2023-02-16 19:10:20 UTC https://padlet.com/392284/4ih53lg67ygr7auk/wish/2485460270 392284 https://padlet.com/392284/4ih53lg67ygr7auk/wish/2485460549 The Law of Conservation of Energy states that energy cannot be created or destroyed. This means that energy cannot just appear or disappear magically. Energy can only go through transfers and transformations. So no, energy cannot be created or destroyed. This is because if it could, that would be breaking scientific laws.]]> 2023-02-16 19:10:34 UTC https://padlet.com/392284/4ih53lg67ygr7auk/wish/2485460549 392284 https://padlet.com/392284/4ih53lg67ygr7auk/wish/2493023590 In this PhET Lab, there is a system which includes a faucet, a wheel and a lightbulb. Mechanical energy transfers from the running water to the wheel, then that energy is transferred to electrical energy and is moving through the cord. The electrical energy has now reached the lightbulb and now, there is an energy transformation that occurs, in which the electrical energy turns into thermal energy. Lastly, the thermal energy becomes light energy that escapes the bulb, with some waste thermal energy escaping as well. Therefore, energy flows in a system by transferring from one object to another, and from changing from one form to another. ]]> 2023-02-23 19:07:16 UTC https://padlet.com/392284/4ih53lg67ygr7auk/wish/2493023590 392284 https://padlet.com/392284/4ih53lg67ygr7auk/wish/2498704638 Energy is the ability to do work. An object that has energy can perform work. Work is applying a force to move or change something. Therefore, something that has energy can apply a force. Energy can interact with tangible objects and cause them to move or change. Energy can also be used to maintain a process or carry out an action.]]> 2023-02-28 22:54:10 UTC https://padlet.com/392284/4ih53lg67ygr7auk/wish/2498704638 392284 https://padlet.com/392284/4ih53lg67ygr7auk/wish/2498707985 Energy can transfer from one object to another. It can also transfer from one location to another. This movement of energy is called energy transfer. Energy transfer involves the movement of the same form of energy. ]]> 2023-02-28 22:59:02 UTC https://padlet.com/392284/4ih53lg67ygr7auk/wish/2498707985 392284 https://padlet.com/392284/4ih53lg67ygr7auk/wish/2498709434 Energy cannot be created or destroyed, but it can change from one form to another. Energy transformation is the conversion of energy from one form to another. An example of this is a basketball hitting the ground, in which mechanical energy is transformed into sound energy.]]> 2023-02-28 23:00:53 UTC https://padlet.com/392284/4ih53lg67ygr7auk/wish/2498709434
