energy 1
What makes heat rise?
As the molecules heat and move faster, they are moving apart
Are there different types of black holes?
stellar-mass, supermassive, and intermediate-mass.
what energy do we use everyday?
all of them
What goes up but never ever comes down?
rain
name the different types of energy
thermal energy, electric energy, radiant energy, chemical energy, nuclear energy,
What never asks a question but gets answered all the time?
the doorbell
How do free energy machines work?
The machine is plugged into an electrical source, which gets the motor's wheel spinning. The machine is then unplugged and the wheel keeps spinning under its own inertia
Is ionizing radiation always harmful?
no
Can you go fast enough to get enough mass to become a black hole?
An object can never be turned into a black hole
How do levers create energy if the conservation of energy does not allow energy to be created?
Levers convert a small force applied over a long distance to a large force applied over a small distance
Name 4 black holes
1. strella
2.intermediate
3.supermassive
4.miniature
Light has no mass so it also has no energy according to Einstein, but how can sunlight warm the earth without energy
Light indeed carries energy via its momentum
What are the different types of potential energy?
gravitational energy, chemical energy, electric energy, nuclear energy,
What two things can you never eat for breakfast?
Lunch and dinner
How can a material at a certain temperature have all of its molecules at the same energy?
It is impossible for the molecules of a material to have the same energy
Is a black hole a 2D or a 3D object?
3D
Can momentum be hidden to human eyes like how kinetic energy can be hidden as heat?
In a regular mechanical system with macroscopic parts, momentum can not be "hidden" to human eyes.
What gets wetter the more it dries?
a towel
Why do diamonds last forever?
At high pressure, diamond is the most stable configuration of pure carbon and not graphite
What word is spelled incorrectly in every single dictionary?
There is no word that is spelled incorrectly in all dictionaries
How can a material at a certain temperature have all of its molecules at the same energy?
It is impossible for the molecules of a material to have the same energy.
Why is mass conserved in chemical reactions?
because the new substances created are composed of atoms that were present in the reactants
Can momentum be hidden to human eyes like how kinetic energy can be hidden as heat?
In a regular mechanical system with macroscopic parts, momentum can not be "hidden" to human eyes.
What are some other ways to save energy in a car besides turning off the air conditioner and rolling down the windows?
Parking in the shade if possible
