In summary, gravity is the weakest of the forces in general, but it is the dominant one at astronomical scales because it has the longest range and because there is no negative mass.

## Which force is long range force?

Long range force

A force that does not need contact between objects to exist. One example is the gravitational force (weight).

## Which are the two long range forces?

There are four fundamental interactions known to exist: the gravitational and electromagnetic interactions, which produce significant long-range forces whose effects can be seen directly in everyday life, and the strong and weak interactions, which produce forces at minuscule, subatomic distances and govern nuclear …

## Which force is strongest?

The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. It’s 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website.

## Which is the shortest range force?

We should know that the strong nuclear force has the shortest range among all the four fundamental forces. The range of the strong nuclear force is 10 times shorter in order of magnitude.

## What are the 4 properties of force?

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.

## Is normal force a contact force?

The normal force is the force that surfaces exert to prevent solid objects from passing through each other. Normal force is a contact force. … It makes sense that the force is perpendicular to the surface since the normal force is what prevents solid objects from passing through each other.

## What are the 5 forces of nature?

The forces controlling the world, and by extension, the visible universe, are gravity, electromagnetism, weak nuclear forces, and strong nuclear forces.

## How weak is gravity?

Gravity is weak because the masses of elementary particles are so small. Gravity has a natural mass unit, mp = √ℏc/G, the Planck mass, which is about 10−5 g. The proton is 22 orders of magnitude less massive. So the stuff which makes up the world is elementary particle “styrofoam stuff” which gravity couples to.

## What is r in free body diagram?

R -> Contact force between table and book. (2) Free body diagram for a object slowing down with friction on a horizontal floor. mg -> Weight of the book. R -> Contact force between table and book. f -> Friction force between the object and horizontal floor.

## What is the weakest force?

Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.

## What is the strongest non contact force?

The strong nuclear force is the strongest force in nature; however, its range is small (acting only over distances of the order of 10−15 m).

## Is love the strongest force on earth?

Einstein said, “If instead of E = mc2, we accept that the energy to heal the world can be obtained through love multiplied by the speed of light squared, we arrive at the conclusion that love is the most powerful force there is, because it has no limits.” …

## Which has shortest range?

Which of the following Force has shortest range? (a) Strong Nuclear Force (b) Electromagnetic Force (c) Gravitational Force (d) Weak Nuclear Force. (a) Strong nuclear force has the shortest range of all the given force. It is the force with which protons are held together in a nucleus.

## How many times is the strong nuclear force stronger than the electromagnetic force?

As its name suggests, the strong force is the strongest—it’s 100 times stronger than the electromagnetic force (which binds electrons into atoms), 10,000 times stronger than the weak force (which governs radioactive decay), and a hundred million million million million million million (1039) times stronger than gravity …

## What is the strength of the electromagnetic force?

Electromagnetic Force: This is the second strongest force after the strong force and it acts on electrically charged particles. It has strength of 1/137 relative to the strong force but has an infinite range.
