Question

what is gravity?.......

Answer 1

Answer:

ᴛʜᴇ ᴀɴsᴡᴇʀ ɪs :::

Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides

Gravity is a force that attracts a body towards the centre of the earth, or towards any other physical body having mass.

Examples of Gravity

A few examples of gravity at work are:

• The gases in the sun are held together by gravity.

• Gravity is responsible for water to rest at the bottom of a glass instead of hovering over at the top of the glass.

• The force of attraction between the earth and the moon causes tides in the ocean. This is the result of gravity.

• Gravity causes the moon to revolve around the earth.

Gravity has the same effect on all objects. If you drop an iron road and a feather, they will fall at the exact same speed. Due to the effect of air resistance on gravity, it might look like the iron rod falls at a greater speed. However, if they were dropped in the vacuum, they would fall at the exact same time. The gravity of an object depends on its size. To be more specific, the Gravity of an object depends on the mass of that object. It is undoubtedly the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter.
