Write a paragraph or story to explain the transformation between potential and kinetic energy as shown in the picture below. • you should have at least 5 complete sentences with a main idea and supporting details. include the following words: o potential energy o kinetic energy o mechanical energy o conservation of energy

Explanation:

At the top of the roller coaster, it was a lot of potential energy but as it starts going down the potential energy descrases and kinetic energy rises. Then as it's going back up again the kinetic energy descrases and  potential energy rises again.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
