Energy in the universe Quick Check

Answer 1

Sure! Here’s a quick overview of energy in the universe:

1. Types of Energy:

   • Kinetic Energy: Energy of motion, found in moving objects, particles, and waves.
   • Potential Energy: Stored energy, such as gravitational potential energy or energy in chemical bonds.
   • Thermal Energy: The energy related to temperature and the motion of particles in a substance.
   • Nuclear Energy: Energy stored in the nucleus of atoms, released during nuclear reactions.
   • Electromagnetic Energy: Energy from electromagnetic waves, including light, radio waves, and microwaves.

2. Conservation of Energy: The total energy in a closed system remains constant. Energy can change forms but cannot be created or destroyed.

3. Dark Energy: A mysterious form of energy that makes up about 68% of the universe, driving its accelerated expansion.

4. Dark Matter: Comprising about 27% of the universe, it influences gravitational forces but does not emit light or energy detectable by current instruments.

5. Standard Model of Cosmology: The Lambda Cold Dark Matter (ΛCDM) model describes the composition of the universe as 5% ordinary matter (atoms), 27% dark matter, and 68% dark energy.
