10 Questions
In physics, what is gravity and what does it cause between all things that have mass?
Gravity is a fundamental interaction that causes mutual attraction between all things that have mass.
How does the strength of gravity compare to the other fundamental interactions?
Gravity is approximately 1038 times weaker than the strong interaction, 1036 times weaker than the electromagnetic force, and 1029 times weaker than the weak interaction.
What does gravity determine the motion of at the macroscopic scale?
Gravity determines the motion of planets, stars, galaxies, and even light at the macroscopic scale.
At what scale does gravity have no significant influence?
Gravity has no significant influence at the level of subatomic particles.
What are the two types of chemical bonds mentioned in the text?
The two types of chemical bonds mentioned in the text are ionic bonds and covalent bonds.
What are some of the important biological functions of gravity mentioned in the text?
Gravity helps to guide the growth of plants through the process of gravitropism and influences biological functions.
What are some examples of 'strong bonds' or 'primary bonds' mentioned in the text?
Some examples of 'strong bonds' or 'primary bonds' mentioned in the text are covalent, ionic, and metallic bonds.
What are some examples of 'weak bonds' or 'secondary bonds' mentioned in the text?
Some examples of 'weak bonds' or 'secondary bonds' mentioned in the text are dipole–dipole interactions, the London dispersion force, and hydrogen bonding.
How are electrons shared between two nuclei attracted to both of them?
Electrons shared between two nuclei will be attracted to both of them due to 'Constructive quantum mechanical wavefunction interference' stabilizing the paired nuclei.
What maintains an optimal distance between bonded nuclei?
Bonded nuclei maintain an optimal distance (the bond distance) balancing attractive and repulsive forces.
