We use a spectrometer to help us determine what stars and planets are made of by passing a light through various chemical elements, different spectral patterns are created. By matching those patterns up to patterns generated in a laboratory environment we can tell what the composition of a distant star or planet is.
Good morning.
Yes, it is possible.Energy is a scalar quantity. The value of the potential energy is calculated the following way:
Where
m is mass,
g is the acceleration of gravity and
h is the height.
Note that the height depends on the adopted referential, therefore, if we adopt, for example, a referential on the floor, if we dig a hole that has a depth of 1 meter, a ball that is put inside the hole will have negative potential energy due to the adopted referential, since
h is negativa in this case.
Answer:
Potential Energy
Explanation:
Potential energy is the energy stored in an object due to it's position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
