What are Examples of Gravity?

Objects with mass exert gravitational or attractive forces on other masses. Gravity keeps the planets in orbits around the sun and the moon around the earth. We rarely think about gravity and examples of gravity in our daily lives, but we need to realize that gravity determines how we interact with the world. We grow within that limit and our heart, muscles, and balance systems depend on it. Gravity is considered one of the fundamental forces of the universe. In this article, let’s understand what objects have gravity and why is gravity important in everyday life.

1. What is Gravity?

Gravity is defined as the force through which a planet or object pulls another object toward its center. All planets remain in orbit around the sun due to gravity.

Why do I fall to the ground when I jump instead of floating in space? Why do things fall when I throw or drop them? The answer is gravity, an invisible force that pulls objects together. Earth’s gravity holds you to the ground and makes things fall from any height. (See How to achieve zero gravity?)

2. What Type of Force is Gravity?

Gravity is a form of many forces. Gravity is the universal fundamental force that acts on and affects all non-zero mass objects. It’s a non-contact force, inherently always attractive, i.e always attracts objects towards it. (See What is Pulling Force?)

3. What are Examples of Gravity?

Gravity is the mutual attraction of two bodies in space. There are many examples of gravity because gravity refers to the invisible force that pulls matter together. Everything has gravity, including people.

Some objects have much more gravity than others. For example, Earth has more gravity than humans. Therefore, falling objects are not attracted by people and fly away, but are attracted to the earth and return to the earth. Learn What are the Different Types of Motion with Examples?

Examples of gravity are: 

• The power that keeps gas in the sun.
• The power to return a ball thrown in the air.
• The force with which the car rolls downhill, even when the accelerator is not pressed.
• The force with which a dropped glass falls to the ground.
• The force that keeps the earth and all planets in their proper positions in orbit around the sun.
• The force that causes an infant to slide down any sliding object.
• The force with which the moon revolves around the earth.
• The force that keeps any planet revolving around the sun.
• The power of the moon causes the tides of the oceans.
• The force that the drink rests on the bottom of the glass instead of floating near the top of the glass.
• The force of an apple falling from an apple tree.

4. What are the Types of Gravity?

Types of gravity and its waves are: 

• Continuous Gravitational Waves.
• Compact Binary in Spiral Gravitational Waves.
• Stochastic Gravitational Waves.
• Burst Gravitational Waves.

5. What are 5 Facts about Gravity?

The 5 amazing facts about gravity are: 

• Gravity is actually not a force.
• The fridge magnet is actually stronger than the Earth’s gravity.
• Some big and heavy objects have the ability to make gravitational waves.
• Gravity on Earth is different in different places.
• Quantum mechanics and gravity are at variance.

6. What is Gravity used for?

Gravity keeps all the objects on planet earth intact. There are many ways gravity is used for. Some examples of gravity are:

• Track Earth’s water and ice.
• Provide energy.
• Give a boost to spacecraft.
• Weigh the unweighable.
• Use gravity as a telescope.
• Hunt for planets around other stars.
• Investigate unseen planets.
• Probe the interiors of planets and moons.
• Save the Earth.
• Probe black holes and the Big Bang.

7. What Objects have Gravity?

Any object or thing in this world which has a mass greater than 0 experiences gravity. For example, the star, moon, and even you have gravity. (See Weight of earth and Moon)

8. Why do Objects have Gravity?

Gravity can be defined as the effect that mass and matter have on time. In relativity, mass slows down time. Gravity can be easily described as how matter moves through space-time. Each particle of matter causes a slight time difference between itself and the surrounding space it occupies. When matter gathers together to form a large object with mass, time slows further as the mass increases, because the time difference is aggregated, and matter always moves towards the slowest time in its vicinity. It causes gravitational effects depending on the magnitude of the mass.

The greater the mass, the slower the time, and the greater the gravitational force on the space it occupies. The reason why matter moves in the direction of the slowest time is due to the property of entropy. All matter moves to its simplest state, including rest. All matter naturally decays, loses heat, and moves toward the slowest time created by the largest crowd, unless some external force acts on it. (See How much is an atmosphere in Depth)

9. Why is Gravity Important in Everyday Life?

Gravity is very important to us. Without them, we will not be able to live on this planet. The gravitational force of the sun causes the earth to orbit around the earth, so we can keep a comfortable distance to enjoy the sun’s light and warmth. It reduces our atmosphere and the air we need to breathe. Must read What are Examples of Pulleys in Everyday Life?
