They are in no particular order gravity, electromagnetism, the weak nuclear force and the strong nuclear force.

What is the strongest force in the world?

strong nuclear force

What are the 7 forces?

Action-at-a-Distance Forces

  • Applied Force.
  • Gravitational Force.
  • Normal Force.
  • Frictional Force.
  • Air Resistance Force.
  • Tension Force.
  • Spring Force.

Which is weakest force in nature?

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.

Which force is weak?

Weak interaction, also called weak force or weak nuclear force, a fundamental force of nature that underlies some forms of radioactivity, governs the decay of unstable subatomic particles such as mesons, and initiates the nuclear fusion reaction that fuels the Sun.

Is weak force attractive or repulsive?

Why is there no gravity in space?

The second reason that gravity is not so obvious in space is because objects tend to orbit planets instead of hitting them. Orbiting just means that an object falls towards a planet due to gravity and continually misses it. ... Astronauts in orbit around the earth are not experiencing "no gravity".

Does the moon have gravity?


Is air present on moon?

On the moon, there's no air to breathe, no breezes to make the flags planted there by the Apollo astronauts flutter. However, there is a very, very thin layer of gases on the lunar surface that can almost be called an atmosphere. ... In the moon's atmosphere, there are only 100 molecules per cubic centimeter.

Was there life on moon?

Crewed exploration of the lunar surface began in 1968 when the Apollo 8 spacecraft orbited the Moon with three astronauts on board. ... The use of a crewed vehicle on the Moon's surface was demonstrated in 1971 with the Lunar Roving Vehicle during Apollo 15.
