Energy
Reducing energy consumption by using less energy or using more energy-efficient devices. Hint: "Saving energy"
Energy Conservation
Electrical energy Changing into light, sound, or thermal energy is an example of what?
Energy Transformation
Which vocabulary word best match the following definition: The change of energy from one type to another, such as Potential Energy to Kinetic Energy
Energy Transformation
The Movement of energy from one object or place to another. For example driving a nail into the wall with a hammer.
Energy Transfer
The internal energy of a substance due to the movement of particles within that substance. Also known as heat energy.
Thermal Energy
The measure of the amount of molecular motion related to the average kinetic energy of these particles.
Temperature
You are at the park pushing your baby sister on a swing. When the swing stops moving does it lose all the energy? Where did the energy go? Explain.
No the energy isn't lost, According to the Law of Conservation of energy Energy can not be destroyed (lost) or created it can Transfer or Transform...( System )
Explain the energy transfer that is happening in the swing.
Kinetic energy from the person is transferring into the swing when they push and make contact with the swing.
Explain the energy transformation that is happening in the swing.
Kinetic Energy from the swing transforms into potential & kinetic energy as it swings from front to back.At the end because of friction it changes to thermal.
The soccer players ate a granola bar and drank water before the Soccer game. The game started and the soccer players began to run and kick the ball around. After a few minutes, they started to sweat. What energy types are present?
Motion (Running) , Chemical (food & water) , Thermal (sweat), Potential (Soccer ball)
Soccer players ate and drank water before the game, at the end of the game they fell very tired. Did the soccer players loose all of their energy at the end of the game ? Why or Why not?
No, the energy was transformed into other forms of energy and was also transferred into the surrounding system/environment
