Gravity-Velocity: Clarifying the Confusion

In summary, there is some disagreement regarding the concept of an increase in gravity with an increase in relativistic mass. It is important to properly cite sources and consider the validity of the information before making any conclusions.

Please excuse my ignorance as I request some clarification. I was researching the possible increase in gravity as a body's velocity increases and there was so ambiguity for some were saying that gravity does increase with an increase in relativistic mass while others were denouncing this concept. Any clarification would be very much appreciated.

If you have found a source that says that "gravity does increase with an increase in relativistic mass", there are two possibilities:
1) Either you have misunderstood what you read; OR
2) What you read is just plain wrong.
However, there is no way for us or anyone else to tell which it is if you will not tell us what you've been looking at.

This thread is closed; when you are ready to cite your sources properly you can PM any of the mentors (or just report this post) and we can reopen it for you. In the meantime, you should read Orodruin's Insights article on what relativistic mass is (and is not) and why the concept is seldom used these days.
 

FAQ: Gravity-Velocity: Clarifying the Confusion

1. What is the difference between gravity and velocity?

Gravity is a force that pulls objects towards each other, while velocity is the rate at which an object's position changes over time.

2. How are gravity and velocity related?

Gravity and velocity are related through the laws of motion. The force of gravity affects the velocity of an object by either increasing or decreasing its speed.

3. Does gravity affect velocity?

Yes, gravity can affect the velocity of an object. For example, when an object is thrown upwards, the force of gravity will eventually slow it down until it reaches its highest point and then pull it back down, increasing its velocity towards the ground.

4. Can velocity exist without gravity?

Yes, velocity can exist without gravity. In space, where there is very little gravity, objects can still have velocity due to their inertia. Inertia is the tendency of an object to maintain its state of motion.

5. How do gravity and velocity affect each other in free fall?

In free fall, gravity and velocity are directly related. As an object falls towards the ground, its velocity increases due to the force of gravity. However, as it falls, air resistance can also affect its velocity and cause it to reach a constant terminal velocity.
