earth rotation on its axis causes gravity to occur on earth
True. Gravity on the moon is about one-sixth that of Earth's gravity.
State what you meant 'the following' to be.
gravity
The force that pull us towards the Earth's surface is the force of Gravity.
It is true that mass and gravity are proportional to one another.
Yes, that is true. As a battery discharges, the concentration of sulfuric acid in the electrolyte decreases, leading to a decrease in density or specific gravity. This change in electrolyte density can be used as an indicator of the state of charge of the battery.
The liquid state is meant as a state of matter.
gravity is the force that pulls everything down towards the centre of the earth.
No, there is no "anti-gravity button" in a spaceship. Spacecraft can create the sensation of weightlessness by achieving a state of free fall around a planet or other celestial body, but true anti-gravity technology does not currently exist.
No, gravity doesn't cause the Earth's rotation.
