Velocity from using only weight mass and kilogram force?

AI Thread Summary
Velocity in space can be calculated using the formula V = at, where 'a' is acceleration derived from force and mass. To find acceleration, convert the thrust from tons to Newtons and apply Newton's second law (F = ma). The discussion clarifies that mass should be in kilograms and force in Newtons, emphasizing that kilograms or tonnes are not forces. The time duration for which the force is applied is crucial for determining the resulting velocity. Understanding these principles allows for accurate calculations of velocity in a vacuum environment.

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

F = ma everywhere

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"?
 

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
