A new roller coaster is advertised as having a perfectly efficient (energy is conserved) first drop without the presence of an additional applied force. Upon riding this roller coaster, a group of students question whether the roller coaster is actually perfectly efficient and want to design an experiment to test this question. The students hypothesized that inclined surfaces approach perfect efficiency as the surface increases in steepness. Design an experiment to test the hypothesis stated by the students above. The student has equipment that is typically found in a high school science laboratory. Identify the variable that will be directly manipulated.

! 55 !  

write a paragraph or story to explain the transformation between potential and kinetic energy as shown in your picture or model.  

you should have at least 5 complete sentences with a main idea and supporting details.  

you must include the following words:  

potential energy

kinetic energy

mechanical energy

conservation of energy

dude, this is hard lol : ))

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
