What is Gravity?
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun. Earth’s gravity is what keeps you on the ground and what makes things fall.
Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.
Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That’s what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.
Gravity is also what keeps the moon in orbit around Earth. And the gravity of the sun keeps all the planets in orbit around it.
The force of gravity is always attractive. It pulls objects together. But it can also act over long distances. For example, the gravity of the sun pulls on Earth. And Earth’s gravity pulls on the sun. They orbit each other because they are mutually attracted to each other.
What do You Mean by Gravitational Force
Gravitational force is the force of attraction between two masses. It is what keeps the planets in orbit around the sun and what makes objects fall to the ground. The force of gravity is weaker than other forces, such as the electromagnetic force, but it is much stronger than the force of friction.
What is the Gravitational Force of Earth
on the Moon
The gravitational force of Earth on the Moon is 1.98×10^20 N.
Gravity on Earth is Not the Same Everywhere
The typical person may believe that the Earth’s gravity is uniform and constant, but this is not actually the case. The gravity on Earth is not the same everywhere. The Earth’s gravity is affected by a number of factors, including the Earth’s rotation, the presence of mountains, and the distribution of mass within the Earth. The gravity on Earth is strongest at the poles and weakest at the equator.
The Earth’s gravity is affected by its rotation. The faster the Earth rotates, the weaker the gravity. This is because the centrifugal force caused by the Earth’s rotation counteracts the force of gravity. The Earth’s gravity is also affected by the presence of mountains. Mountains can deflect the Earth’s gravity, making it weaker in some areas and stronger in others. Finally, the distribution of mass within the Earth can also affect the gravity. If the Earth’s mass is not evenly distributed, then the gravity will be weaker in some areas and stronger in others.
Examples of Gravity
The force that keeps people and objects on the ground is an example of gravity. The force that pulls objects towards the center of the Earth is another example of it. The force that causes the tides is also an example of it.
