An object that has energy can do work. Energy can be both Kinetic or Potential energy. Kinetic energy is energy of motion and energy used when something is moving. Potential energy is stored energy and energy waiting to be used. There are a lot of different types of energy the six main types of energy are mechanical, electrical, sound, thermal, light, and chemical.]]> 2021-03-17 18:37:43 UTC https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1322253466 5128691 https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1322326598 In science work means something a little different from having a job type of work.  Work is applying force, to move or change something. Therefore, something that has energy can apply a force. ]]> 2021-03-17 18:54:05 UTC https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1322326598 5128691 https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1343630587 The law of conservation of energy states that, "Energy cannot be created or destroyed, but it can change forms.  What this means is energy doesn't just randomly appears it changes into different types of energy. ]]> 2021-03-23 15:45:19 UTC https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1343630587 5128691 https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1343667400 Mechanical energy is energy that an object has due to its motion or position. This energy is used to move lift and hold objects. Some examples of mechanical energy is a bicycle, because it is moving, wind has mechanical energy because it is moving air, like a wind turbine. And a hammer has mechanical energy because it moves to hammer a nail.]]> 2021-03-23 15:51:34 UTC https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1343667400 5128691 https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1343715526 Electrical energy is electricity, it is carried by charged particles. Those particles can build up an object and creates static electricity. If those particles move from one place to another this creates current electricity. This electricity moves along a path called a circuit. Some examples of electrical energy include a light bulb a washing machine, TV and phone charger.]]> 2021-03-23 15:59:32 UTC https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1343715526 5128691 https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1343768094 Sound energy is carried by sound waves, they travel through matter. This type of energy is created when an object vibrates, this object then produces sound and therefore sound energy. Some examples of sound energy is a radio, any type of instrument and the popping of a balloon.]]> 2021-03-23 16:08:32 UTC https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1343768094 5128691 https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1343795008 Thermal energy is related with temperature, the amount of thermal energy in a substance has to do with the substances temperature as well as the amount in that substance. Some examples of thermal energy is the warmth of the sun, baking in an oven, a hand warmer and a camp fire. ]]> 2021-03-23 16:12:58 UTC https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1343795008 5128691 https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1343818196 Light energy is carried by light, which basically refers to visible light. Light energy is more accurately called radiant energy. Some examples of light energy is a lit candle, a flash light, fire, a lamb and a bulb.]]> 2021-03-23 16:16:46 UTC https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1343818196 5128691 https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1343840793 Chemical energy is stored energy within bonds between atoms of matter, it is used to keep atoms bonded together. Some examples of chemical energy is food and fuel store a lot of chemical energy. The bonds break and chemical energy is released, when a person digests food. The same goes for fuel.]]> 2021-03-23 16:20:30 UTC https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1343840793 5128691 https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1345952383 Yes energy can change. Because all of the six main types of energy can change from one to another. For example, when you turn on a light bulb it changes from mechanical energy to light energy and some thermal energy. Also a blow dryer would be an example that energy can change. So yes, energy can change.]]> 2021-03-24 02:13:30 UTC https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1345952383 5128691 https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1345980335 No, energy cannot be created or destroyed, instead it changes from one form to another. Energy is the ability to do work and it is also matter. The law of conservation of matter states that matter cannot be created or destroyed. The law of conservation of energy states that energy cannot be created or destroyed, instead it changes in form, therefore energy cannot be created or destroyed.]]> 2021-03-24 02:24:04 UTC https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1345980335 5128691 https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1345998015 An object can transfer more than one type of energy. For example a blow dryer, it can transfer electrical energy, thermal energy and sound energy. Another example is a campfire it can transfer thermal energy and light energy. There is also something called waste energy. Waste energy is energy not needed in a system or an object. If you look at where the most energy is flowing and you find some energy not following that flow, it's "waste."]]> 2021-03-24 02:31:03 UTC https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1345998015 5128691 https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1346040289 The way that energy flows in a system is by changing form. For example, in this picture you can see that because the girl is biking, the chemical energy changes into mechanical energy, then it changes into electrical energy, and lastly thermal energy. You can see that the energy keeps changing forms and flows through the system. You can even see that there is some waste energy when the girl is biking because some thermal energy is not following the flow and instead floating up in the air.]]> 2021-03-24 02:47:28 UTC https://padlet.com/5128691/h4udfhkbb0rret7s/wish/1346040289
