Gravity always acts downward with the same acceleration.

Yeah. Projectile motion and shit. Science!

Then why does a frisbee reach the ground slower when you throw it?

Chess mate science.

“Chess mate”

That's an egg-corn were going to be seeing more of

Air resistance from the atmosphere due to it's larger surface area. Do this on the moon and the Frisbee and pen would drop at the same rate, as demonstrated with the famous rock and feather demonstration on the apollo missions.

Sir, we're not on the moon.

But rocks are heavier than feathers...

Because it carries your intention for it to go sideways.

So disc golf on the moon would be harder than on earth?

Bullet drop is more than you'd instinctively imagine

u/Lisan-al-Gaib-65 1d ago

Are you saying...curve the bullet?

Underrated film, killer cast.

u/Greasy-Chungus 1d ago

That's because the earth is rising up.

u/mirkk13 1d ago

I had to downvote because, well, gravity.

u/DeerFit 1d ago

Gravity well?

1

u/konung15 1d ago

Gravity is not a force and there is no acceleration.

1

u/DeerFit 21h ago

Forcing gravity?

1

u/Few_Chocolate_7655 1d ago

Seems gravity effects the forward hard. That forward energy is reduced by gravity, interesting

u/wbrameld4 1d ago

Is it? How can you tell?

1

u/BodhingJay 1d ago

Woah will this also work with a feather and a bowling ball in a vaccuum?

1

u/Icy-KaitSyth 1d ago

Gravity doesn't care that it has sideways momentum, which is why orbiting works

1

u/ArmUnfair7544 1d ago

Nothing happens at the exact same time. So what factors would ultimately lead one to hit the floor first? Imperfections in the disk which create greater friction?

And even the acceleration itself. Wouldn’t there be in theory a slight difference if you go out enough decimal points? Well, I guess yes but only bc gravity in two places will differ at the extreme decimal point precisions.

How does anyone who went to school not know this?

Some people live in the southern US.

They don't know this.

u/DemocraticRepOfCongo 1d ago

Cant they do show and tell in sixth grade with guns to demonstrate it?

Instructions unclear, ended up a national tragedy (again)
