# Gravity interaction is possible between

• silent10
In summary, gravity interaction is possible between both material objects and electromagnetic waves, as proven by Einstein's theory of relativity which states that even objects without mass can experience gravity through the relationship between mass and energy. This means that both material objects and electromagnetic waves can experience gravity through acceleration and motion, making option C the correct answer.

Gravity interaction is possible between:
B.Material objects.
C.Both material objects and electromagnetic waves
D.None

Can someone tell me its ans with reasons?

Generally, per the PF guidelines, you should show your work or at least share your thoughts on the subject before you can receive help. So.. what do you think?

Im confused between b) and c)
Even objects without mass can experience gravity, E=MC squared (mass-energy equation ) related mass to energy. Einstein proved Acceleration and motion are forms of gravity in different inertial frames, the theory of relativity.
Am I right?

Then your reasoning should come down to whether or not you can cite an example of an EM wave interacting with gravity.

I can confirm that gravity interaction is indeed possible between both material objects and electromagnetic waves. This is because gravity is a fundamental force that affects all objects with mass, regardless of their composition or properties. This includes both material objects, which have mass, and electromagnetic waves, which do not have mass but can still be affected by gravity due to their energy and momentum. Therefore, it is important to consider both material objects and electromagnetic waves when studying gravity and its effects.

## 1. What is gravity and how does it work?

Gravity is a fundamental force of nature that causes objects with mass to attract each other. It is described by Isaac Newton's law of universal gravitation, which states that the force of gravity between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them. This means that the larger the masses of the objects and the closer they are to each other, the stronger the force of gravity will be.

## 2. Can gravity only occur between objects with mass?

Yes, gravity can only occur between objects with mass. The more mass an object has, the greater its gravitational pull will be. This is why the Earth has a much stronger gravitational pull than smaller objects like a basketball or a pencil.

## 3. Is gravity a long-range or short-range force?

Gravity is a long-range force, meaning it can act over very large distances. In fact, the force of gravity between two objects never completely disappears, no matter how far apart they are. However, the strength of the force does decrease as the distance between the objects increases.

## 4. Can gravity interact with other forces?

Yes, gravity can interact with other forces. In fact, gravity is one of the four fundamental forces in nature, along with electromagnetism, the strong nuclear force, and the weak nuclear force. These forces can all act on an object simultaneously and can sometimes even cancel each other out.

## 5. How does gravity interact with space and time?

According to Einstein's theory of general relativity, gravity is not just a force between objects, but it is also a curvature of space and time. Massive objects like planets and stars bend the fabric of space-time, causing objects to move along curved paths. This is why we experience the force of gravity as an attraction towards the center of the Earth, rather than being pulled straight down.
