Is there no normal force in space?
(B) An astronaut orbiting the Earth does feel weightless because there is no ground or normal force to counteract the force of gravity. However, since the astronaut is also moving forward super fast, he/she continuously falls around the Earth rather than crashing into the Earth.
Is it possible for a body to have no forces acting on it in any place in the universe?
Yes, it is possible to have motion without a force being present. Newton’s first law states that, in fact, an object must continue to move at the same…
What forces are in space?
Gravity is a very important force. Every object in space exerts a gravitational pull on every other, and so gravity influences the paths taken by everything traveling through space. It is the glue that holds together entire galaxies.
What are the forces acting on a body outside in space?
The movement of things in space is influenced by gravity. Gravity is an important force that can change the course of bodies in space or pull them off of one course, or even cause them to crash together.
Why is there no friction in space?
As there is no air in space, there is no friction due to air in space. However, normal surface friction occurs whenever two surfaces rub together. So, even in space, when surfaces slide over each other there is friction. In space, it is the lack of air that prevents air friction from occurring.
What is the difference between saying that no forces act on a body and saying that the net force acting on the body is zero?
The “unless acted upon by a net force” version is more correct. For example, as you stand or sit still, the earth pushes you up with a force equal and opposite to the force with which gravity pulls you down. The net force, or total force, is zero, so you do not move.
What forces are absent in space?
Astronauts float around in space because there is no gravity in space. Everyone knows that the farther you get from Earth, the less the gravitational force is. Well, astronauts are so far from the Earth that gravity is so small. This is why NASA calls it microgravity.
Can a body accelerate if there are no forces acting upon it?
When there are no forces acting on an object at all, it is said to be in “static equilibrium” which means that nothing is happening and the object is not moving. Technically speaking your body, as you sit at your computer or read this off of your phone, is in a conditio Flat answer to the first question: No. It is completely impossible.
Is it correct to say that no force acts on a body at rest?
No force acts on a body at rest; if at least one force acted on it the body would move.
Are there any forces that are present in space?
There are forces in space that are effectually much different from how they effect us in our environment. Yet, they are there just the same. In space, one becomes aware of the difference of Newton’s gravitation and Einstein’s gravitational field.
What happens if there are no particles in space?
If there are no particles present, then we say that space is empty, even if it contains electromagnetic waves and gravitational field lines. At the beginning (or very soon after it) gamma-ray photons were distributed nearly uniformly in all of space.
