a. True b. False
True
There are over 500 kinds of fish that produce electricity. Electric eels and electric rays are examples of fishes that produce electricity.
What is an example of Potential Energy?
Roller Coaster sitting on top of a hill
What is an example of kinetic energy?
a car rolling down a hill
What is the difference between potential and kinetic?
Potential energy is energy waiting to go into motion. Kinetic energy is energy in motion.
What is the energy transformation in the Human body?
Chemical->Motion and heat
How long take for the energy from the sun to reach the Earth?
a. 10 minutes b. 8 minutes
b. 8 minutes
what is an example of potential energy?
A stunt driver at the top of a ramp
What happens to Kinetic energy when two objects collide?
The objects transfer kinetic energy for each other.
Which law states that energy cannot be created or destroyed?
Law of energy of conservation
What is the energy transformation in a flashlight?
Chemical->Electrical, Heat and Light
We can get energy from trash and sewage.
a. True b. False
True
All that waste we flush down the toilet and put in our trashcans doesn't have to go to, well, waste! When waste breaks down, it can release methane, a natural gas. We can trap that gas and use it to make electricity. This is also helpful because methane is a powerful greenhouse gas. If we use it, we keep it out of the atmosphere and in doing so help the environment. Everybody wins!
What is the max potential energy at the top of a roller coaster?
a. 0
b. 2
c. 4
d. 6
d. 6
Kinetic energy decreases as ........decreases?
Kinetic energy decreases as mass decreases.
Why can energy only flow from hot to cold and not the other way around?
You can only take heat away
What is the energy transformation in a campfire?
Chemical->Heat and Light
Is food a form of chemical energy?
Yes!!
While energy facts are typically associated with electricity and power, food is also a form of chemical energy that equips living organisms with the sustenance to grow, repair, and reproduce. This chemical energy is generally measured in calories or joules. Energy is released into the body during digestion and converted into mechanical energy or heat.
How does a roller coaster represent potential energy?
When it goes up it has potential energy
In a roller coaster, when the potential energy is transformed into kinetic energy?
When it is at its highest point then it is potential energy and when it rolls down to its lowest point it is kinetic energy.
How does energy flow when you have ice water and hot chocolate?
The energy flow from hot chocolate to ice water (cold)
What is the energy transformation in a windmill?
Kinetic->Electrical and Mechanical
