Can gravity be considered a force?

Gravity is considered a universal force because it acts between any two masses anywhere in the universe. For example, there is a gravitational pull between the Sun and the Moon. Even small masses attract each other. The force of gravity between dust and gas particles in space helped form the solar system.

Is gravity one of the four fundamental forces?

fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay.

What will happen if there is no gravity on Earth for Class 4?

Humans and other objects will become weightless without gravity. If we have no gravity force, the atmosphere would disappear into space, the moon would collide with the earth, the earth would stop rotating, we would all feel weightless, the earth would collide with the sun, and as a consequence. We would all perish.

How many fundamental forces are there in nature?

There are four fundamental forces in nature – gravitational, electromagnetic, strong and weak nuclear forces. Strong nuclear force is the strongest fundamental force while gravitational force is the weakest fundamental force.

What is the gravitational force of attraction?

Gravitational force is one of the four fundamental forces of nature. It is the weakest of the four. It is also the attractive force which arise from the gravitational interaction.

How strong is the gravitational force of the Earth?

When considered for massive objects, like the sun, or giant planets, gravitational force is considered to be strong as the masses of these objects are also large. On an atomic level, this force is considered weak. The gravitational force of the earth is 9.807 m/s 2.

What is the fourth fundamental force?

But the fourth fundamental force, gravity, is different. Our current framework for understanding gravity, devised a century ago by Albert Einstein, tells us that apples fall from trees and planets orbit stars because they move along curves in the space-time continuum.
