Potential energy is highest at the top of the loop, and kinetic energy is highest at the bottom of the loop.

Answer:

<h2>See below</h2>

Explanation:

Let us first give a formal definition of the terms.

1. Potential Energy: Energy that has the ability to do work, but is stationary at the moment.

2. Kinetic Energy: The energy of an object in motion.

Now that we know the definitions of these terms, we can answer the question. Remember that the area of greatest potential energy is that spot where there is potential to do work, but that energy is not causing any movement at the current time. The spot where there is the greatest amount of potential energy in the image is at the top of the roller coaster. There is little movement at this juncture, but there is plenty of potential energy. As the coaster goes down, the kinetic energy goes up, since the coaster is now in motion. The spot where there is the greatest amount of kinetic energy is near the bottom of the roller coaster.

A powerful missile reaches a speed of 5 kilometers per second in 10 seconds after its launch. What is the average acceleration o

AveGali [126]

Average acceleration = (change in speed) / (time for the change)

The missile's change in speed is (5,000 - 0) = 5,000 m/s

Average acceleration = (5,000 m/s) / (10 sec)

= 500 m/s² (about 51 Gs)

Inconveniently, this isn't one of the choices on the list. Is there something wrong, either with the choices or with my solution ?

No. Relax. Everything is OK.

500 meters is the same thing as 0.5 kilometer. So my answer can also be written as 0.5 km/s² . That doesn't change anything, and it IS one of the listed choices.

The average acceleration is <em>0.5 km/sec² (d)</em> .

If a body accelerates from a state of relative rest in a gravity field, where does the energy come from to transfer as kinetic e

Delvig [45]

The energy that transforms into kinetic energy is the Potential Energy. It happens that objects can store energy as a result of its position. Image for example a slingshot. When you stretch the slingshot, it stores energy, this energy would be the energy you used to stretch the slingshot, the material aborbs it and then release to throw the projectile.

Now, on earth and everywhere in the universe where you are close to an object with mass, it exists a force called gravity that attracts you towards that object. Every object that has mass exercises gravitational attration towards the other objects. It just happens that Earth is has so much mass that its gravitational pull is way stronger that the gravitational pull of another object on its surface. This means things will tend to be as close as earth as possible, and in order to move something away from earth, you will have to perform a force in the opposite direction to Earth and, therefore, consume energy. This energy will be store as potential energy, and when you drop the object, the potential energy will be the energy that will transform to kinetic energy.
