1. at what point in its orbit does the comet have the greatest potential energy? at what point does it have the least potential energy?
2. at what point in its orbit does the comet have the greatest kinetic energy? at what point does it have the least kinetic energy?
3. describe the energy transformations that are taking place as the comet moves from point b to point d.
4. describe the energy transformations that are taking place as the comet moves from point f to point g.
5. what happens to the comet's total energy when it is closest to the sun?
6. what happens to the comet's total energy when it is farthest from the sun?

1. At point A, it's orbit has the greatest potential energy because it is resting. At point E, it's orbit has the least potential energy because that's when the comet is moving the most.

2. At point E, it's orbit has the most kinetic energy because that's when the comet is moving the most. At point A, the comet has the least kinetic energy because the comet is resting.

3. From point B to point D its orbit's potential energy is decreasing and its kinetic energy is increasing meaning it's moving more and more.

4. From point F to point G the comet's orbit's potential energy is increasing and its kinetic energy is decreasing because it's moving less and less.

5. When the comet is closest to the sun, its total energy is released.

6. When the comet is farthest from the sun, its total energy is stored. 

the simple machine has three main features. they are:

loadfulcrumeffort

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
