Answer:
B. Along this path the gravitational potential energy of the system is never zero.
D. At every location along the comet's path the gravitational potential energy of the system is negative.
E. The sum of the kinetic energy of the system plus the gravitational potential energy of the system is the same at every location along this path.
Explanation:
Gravitational potential energy of the system is given as
[tex]U = -\frac{Gm_1m_2}{r}[/tex]
now we know that
[tex]KE = \frac{1}{2}mv^2[/tex]
since the system is bounded to move together so the total mechanical energy must be negative
so sum of kinetic energy and potential energy must be negative at all locations.
Also we know that that potential energy is always non zero and a negative quantity here.
The branch of science that deals with chemical and bonds are called chemistry. Each body has the power to attract each other in the influence of the attraction pull.
From the given statements, statement B, statement D, and statement E are correct.
For the system, the gravitational potential energy is given as below.
What is gravitation force?
- Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are attracted to one another.
- On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the tides of the oceans.
[tex]E= -\dfrac{Gm_1m_2}{ r^2}[/tex]
The gravitational potential energy depends on the distance of the path. Hence it can not be zero along the path and it will be negative along the path.
The kinetic energy of the system is given as,[tex]KE = \dfrac {1}{2} mv^2[/tex]
If the speed of the comet is decreasing then the sum of the gravitational potential energy of the system and kinetic energy of the system will be the same at every location.
Hence, statement B, statement D, and statement E are correct.
