The Impact of External Factors on Projectile Range

In summary, Projectile range is directly proportional to the horizontal distance traveled by the projectile. The shape and weight of the projectile also affect the range.

Projectile doubt...

CHOOSE THE CORRECT ANSWER AND EXPLAIN.

What is the nature of proportionality between the muzzle angle and the horizontal distance traveled by a projectile?

a) Directly proportional.
b) Inversely proportional.
c) None of the above.

Well, what do you think?

Well think about this. The bigger the angle, the higher the projectile goes. The higher it goes, the longer time it takes to reach the ground. The longer it takes to reach the ground,...
You don't even need formulas for this.

True.

Also true.
The longer it takes to reach the ground,...
Not sure what you can immediately deduce from this.
You don't even need formulas for this.
You might want to reconsider that.

Well, what I thought was the longer it takes to reach the ground, the more time it has to travel horizontally, therefore the more horizontal distance it travels. Skipping over, you get:
The bigger the angle, the more horizontal distance it travels.
So they are directly proportional.

So what about the angle of 90 degrees? :-)

Hmm. It does say it is a muzzle angle, so if the angle is 90, then you end up in shooting yourself and then you wouldn't care about the answer anyway. :)

Yeah, I guess my non-formula logic doesn't apply for a 90 angle. Then the answer would be C.

I just realized that if you throw it too high, then Vx will decrease.
So yeah, all my posts don't make sense. Except for the one with the 90 degree angle. :)

Could you say it is proportional to sin(2*angle), then?

What makes you think that?

Am I right?

i too came to Husky's answer before posting the topic. But i had doubts whether it was right or wrong.

let the angle be 'A'.
Let the velocity be 'V'
therefore
horizontal component = V cos A
vertical component = V sin A

therefore
horizontal displacement = V cos A * t(time of flight) units
vertical displacement = V sin A * t units

At maximum height,
V sin A = 0. ----------------> l

consider formula V = U-gt ----------------> ll


therefore substituting l in ll

0 = V sin A - gt
t = (V sin A)/g

total time of flight = 2t
=2((V sin A)/g)

range is nothing but
the horizontal displacement V cos A * t

so range = (2(V sin A)/g} * V cos A

therefore range is directly proportional to Sin2A

Am I right guys?

ya hooooooooooooooooooooo
Thanks guys.
Physics Forums Rok and you guys are cool
the site u gave me is just beyond cool dude How much does wind affect the range of a projectile body?
And how much does the shape and weight of the body affect the range?

FAQ: The Impact of External Factors on Projectile Range

What is projectile doubt?

Projectile doubt is a term used in scientific research to describe the uncertainty or skepticism surrounding a particular theory or hypothesis. It refers to the idea that there may be flaws or gaps in our understanding, and that further investigation is needed to confirm or refute a claim.

How is projectile doubt different from regular doubt?

While regular doubt is a common human response to uncertainty, projectile doubt is a more specific concept within the scientific community. It involves a critical examination of evidence and a willingness to challenge established beliefs, rather than simply questioning or second-guessing without a basis.

What causes projectile doubt?

Projectile doubt can arise from a variety of sources, such as conflicting evidence, new discoveries, or limitations in current research methods. It can also be sparked by a lack of consensus among scientists or the need for further experimentation to fully understand a phenomenon.

How can projectile doubt be beneficial?

While doubt is often seen as a negative or hindering force, projectile doubt can actually be beneficial in the scientific process. It encourages critical thinking and drives the pursuit of new knowledge and understanding. By challenging assumptions and theories, projectile doubt can lead to breakthroughs and advancements in scientific understanding.

Can projectile doubt ever be resolved?

Projectile doubt may never be fully resolved, as it is an ongoing and essential aspect of the scientific process. However, through continued research and experimentation, scientists can work to address and reduce the uncertainty surrounding a particular topic. As new evidence and technologies emerge, our understanding and confidence in a theory or hypothesis may evolve, but there will always be room for further inquiry and doubt.
