Velocity from using only weight mass and kilogram force?

Click For Summary

Discussion Overview

The discussion revolves around calculating velocity using weight mass and thrust force, specifically in the context of a rocket in space. Participants explore the relationship between force, mass, and acceleration without considering gravitational effects.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant questions whether a formula exists to calculate velocity based solely on weight mass and thrust force, providing a specific example of a rocket's weight and thrust.
  • Another participant states the fundamental relationship of force as F = ma, implying its relevance to the discussion.
  • A further reply seeks clarification on the application of the formula, indicating a lack of understanding of the physics involved.
  • Another participant emphasizes that force is measured in Newtons and distinguishes between mass and force, suggesting that velocity depends on the duration of the applied force.
  • There is a request for clarification on what is meant by "count velocity," indicating potential confusion about the terminology used.

Areas of Agreement / Disagreement

The discussion does not reach a consensus, as participants express differing levels of understanding and clarity regarding the concepts of force, mass, and velocity.

Contextual Notes

Participants highlight the need for clear definitions and understanding of units, such as the distinction between mass (in kilograms or tonnes) and force (in Newtons). There is also an acknowledgment that the time duration over which the force is applied is crucial for determining velocity.

Who May Find This Useful

This discussion may be of interest to individuals seeking to understand the basic principles of physics related to force, mass, and motion, particularly in the context of rocketry and space travel.

i was wondering about counting velocity only from weight mass and from kilogram force (like force from rocket thruster)

ex: there's a rocket in space, its weight is 63 metric tons and the rocket thruster output is 128 tons. i won't include the G force, cause i want to look the velocity when it's in space.

is there a formula to count velocity from that kind of category? of course the velocity would be km/h

to make it simple for the kilogram force, i try to convert 128 tons force to Newton, which is 125,5251.2 Newton

um, can you explain...?

i'm a little idiot to physics, so can you please explain step by step how can get that formula to fit the description above...?
 
Force in Newtons, Mass in kilograms and acceleration in metres per second squared.
The velocity will depend on how long the force has been applied. V = at

BTW kilogram or a tonne is not a force. A force is measured in Newtons in SI units.
What do you actually want to know and what do you mean by "count velocity"?
