Did your physics professor say “velocity == speed”? Because if so, yes he was

According to this physics website you’re wrong

An object is accelerating if it is changing its velocity.

Velocity =/= speed

A change in direction is a change in velocity

Here’s a new clearer statement to express my thoughts on the matter.

Contrails are visible and normal and fine. I probably don’t fully understand the science behind them, but I realize what we are seeing is water vapor.

Chemtrails are also real though. They are invisible to the naked eye and are directly contributing to global warming as well as some health concerns that are hard to quantify. They are not some conspiracy to control or disable the masses. The exhaust of cars and especially planes leave a trail of harmful chemicals behind them. The reason for this is because we care more about convenience and money than we do about the ecosystem we live in.

I personally believe pointing out that dichotomy is more useful than laughing at people who are misinformed.

Just because the contrails are science

I understand that part, doesn’t stop them from containing the plane exhaust which is directly contributing to global warming

Nah, plane exhaust is real and killing the planet. Just because the contrails are science and not doing mind control doesn’t mean they’re not still bad.

Pope killed a baby

I would like to do that, but my comments on negative topics definitely produce more discussion. Just like everywhere else, negative is easier than positive.

You’re not wrong but also the only reason this is a real problem is because of American tipping culture

Actual guess after hearing that they’re found with money. Used it to check size of coins for valuation? Sort of like how some coin counters with?
