2.1
What are the things in a system?
Input, Process, Output (extra points if said feedback and flow)
What are the types of KE, and the new types of PE?
KE: Sound, Thermal, Electric, and Electromagnetic
PE: Electric and Nuclear
What are the 3 types of heat transfer.
Conduction, Convection, and Radiation
Types of Non-Renewable
Oil, coal, and natural gas.
What are some PE’s
GPE,EPE, and CPE
How do you get energy from nuclear energy?
Fission and Fusion
Temperature vs Thermal Energy
Temperature, the total energy in all of an objects particles.
Thermal, the average degree of energy of an object.
Types of Renewable.
Solar, wind, nuclear, hydro, geothermal, and biomass.
What is the difference between Transfer and Transform?
Transfer, object to object or location to location.
Transformation, the change of energy from one form to another in different objects.
How to find MKE?
PE+KE
What are the three types of temperature energy.
Metric/Celsius, American/Fahrenheit, Science/Kelvin
How is coal formed, and how is oil and natural gas form?
Coal is formed by dead plants, and oil and gas is both dead plants and animals, and is formed from lots of heat and pressure from being buried underground, forming coal, oil, or natural gas.
The pendulum is in the middle of swinging down, how much GPE and KE does it have and what energy is it gaining?
It had equal GPE and KE, and is gaining KE.
Describe whether this is an energy transfer or an energy transformation?
Hearing music from another room across the house.This is an energy transfer since the sound energy is going from one room to another.
Which has more thermal energy? An iceberg or a lot match?
The iceberg because it has way more particles, and thermal energy is the energy of all the particles in an object.
Non-Renewable vs Renewable
Renewable get replenished in a persons lifetime, and non-renewable takes thousands and thousands of years to form.
What is the equation for both KE and PE
KE=1/2xMxH
PE=MxGxH
What slows down something with KE and why?
Friction slows an object down because of the friction of the object and the air particles, making the objet release heat and lose energy. Gravity pulls down an object and slows it down when it is on a flat surface since the gravity is pulling it in towards earth.
Why is my foot cold when I step on tile but not on carpet?
This is because tile is a conductor so it absorbs heat, so when your foot is one the ground, the heat from your foot is conducted to the tile, making your foot cold. Carpet is an insulator, which keeps heat in, so the heat from your foot doesn’t conduct to the carpet, it stays in your foot.
Energy types vs resource
An energy resources are the ways to get energy.
An energy type is the type of energy something has.
