Question 1: Definitions
1. 1 **Potential Energy:** Potential energy is the energy an object has due to its
position or condition. It is stored energy that can be converted into other forms of
energy, like kinetic energy. Example: A book resting on a shelf has gravitational
potential energy.
2. 2 **Constellations:** Constellations are recognizable patterns of stars in the night
sky. These patterns are formed by stars that appear to be close together from our
vantage point on Earth, although they may be very far apart in space. They are
named after mythological figures, animals, or objects.
3. 3 **Telescope:** A telescope is an optical instrument designed to make distant
objects appear nearer. It works by using lenses, mirrors, or a combination of both to
gather and focus light, allowing us to see objects that are too faint or too far away to
be seen with the naked eye.
4. 4 **Spectrometers:** Spectrometers are instruments used to measure the
properties of light over a specific portion of the electromagnetic spectrum. They
analyze the spectrum of light emitted, absorbed, or reflected by a substance,
providing information about its composition, temperature, density, and other
characteristics.
5. 5 **Circuit:** An electrical circuit is a closed loop that allows electric current to
flow. It typically consists of a power source (e.g., a battery), conductors (e.g., wires),
and components (e.g., resistors, capacitors, switches) that control and utilize the flow
of electricity.
