Weight of an object = the force on the object
This is a fact
If the force required is less, the weight is less
so a 5kg stone that is thrown at the floor isnt 5kg when it hits the floor?
Now I know why you have pissed off everyone of worth on this forum. Get off the Internet, and go to a few first year engineering / physics lectures.
Weight is defined as the force exerted on an object due to gravitational pull. Therefore, w =Fsub(g)=masub(g)=mG (G = g @ surface of 9.8067m/s^2)
It's mass would stay the same.
If you throw a stone upwards in the air, force stops being applied to it (apart from gravity) so it would actually have negative weight - or weigh more depending on which way you look at it (fucking relativity)
because the force of the bands upwards against the bands is making the force of gravity less. And weight = mass * gravitational force
the weight is still the same, just the upward force is greater than the force of gravity. but the force of gravity still applies to the object so it is still the same weight.
>your face when my degree is in engineering
What you're saying is correct but you fail to factor in that net force decreases as force increases against gravity
This is where you are wrong. You have actually finally stated that weight is a function of mass (constant) and gravitational acceleration (NOT FORCE). I get that you mean acceleration, and you agree that gravity is more or less constant. So the force of gravity does not decrease, and the weight does not decrease, but the NET downward force does, due to a positive (or upward) force.
This thread hurts my head...... Cant we talk about squats or something?
No, I don't fail to factor that in, as you'll notice by my next post. If you do have a degree in engineering, then you would benefit from a few English classes, because you have FINALLY denoted that NET FORCE (downward) decreases. Weight (downward force due to gravity only) is constant.
The net gravitational force is negative
I like how you try to insult me
lol oni so highOni has a way of confusing and complicating things that aren't that complicated.
Going back to the original statement that started all this, he said that the weight of the bar DECREASES as speed increases.
Now we all know that this just doesn't happen, a 240kg bar will always be a 240kg bar no matter how fast you try and move it.
Then he went on a tangent about relativistic mass and what not and confusion ensued.
The net FORCE is negative. The gravitational force is constant. If you want to argue a subject that you actually finally appear to know something about, be very specific with your terminology. Because you're contradicting yourself in your terms.
It's mass would stay the same.
If you throw a stone upwards in the air, force stops being applied to it (apart from gravity) so it would actually have negative weight - or weigh more depending on which way you look at it (fucking relativity)
The stone doesn't weigh less because you threw it into the air FFS, it moved upwards because an opposite force was applied to it, it's mass AND weight would be the same.
weight = force
you weigh nothing freefalling out of a plane, your mass is the same
