Dammit, Dad!!!

When I told her the Moon has gravity and the Sun has A LOT of gravity she told me I was kidding so when I told her that even she has a little bit of Mary gravity she really thought I was kidding I think :laughing:

When I was in high school, our teacher talked about how all matter has gravity. She asked the class “have you ever noticed when you walk next to a really tall building you feel a slight pull toward it?”. Some kids started nodding. She then said “that doesn’t happen”. Funny enough I still remember 25 years later.

Tonight our 6yo son told my husband, “Dad, do you know what I’m doing right now? I’m persevering in roblox! That’s important. It means never giving up. It’s kind of like patience. Which is important too."

He is wiser than I am some days.[/quote]
No, it means he hopes you let him play more Roblox.

We are indeed accelerating.

There is centripetal acceleration though the center of the spinning axis.

Plus, acceleration is Δv which is either a change in magnitude (speed) or direction. We are constantly changing direction along the rotation of the earth. Therefore we are accelerating.

Plus, the earth is accelerating around the sun…

When I teach that part I usually get up on a chair and tell the students to watch reallllly carefully when I jump off to see that the earth jumps up to meet me. :joy:
Then I try to get across to them how mind-bogglingly large the mass of earth is. Hope it sticks with some of them.

My son had an incredible touchdown catch in flag football yesterday. Then he dropped a dime as QB on a TD throw later in the game. Tight spiral, prolly 25 yards in the air, hit the kid in stride.

My oldest found out yesterday that they were earned a $20K scholarship to their school of choice. They now have an opportunity to have full tuition covered.

Congratulations!!!

TIL, it seems like what you feel is acceleration, but since ground, you, air, etc are all accelerating together your relative acceleration is 0 (aka you’re all spinning together) and so you don’t feel it?

Has nothing to do with “feeling it.” If you are changing direction, you are accelerating.

Okay, then how do you explain the fact that we don’t feel the Earth spinning?

Obvs not a brag on you parent’s physics knowledge thread. Objects on the surface of a spinning object do in fact, undergo acceleration.

Ninja’d.

Quick google gives : The centripetal acceleration is about 3.39 cm/sec^2 at the equator (I’m getting this number from the CRC Handbook of Chemistry and Physics), which is about 0.35% the acceleration of gravity at the surface of the earth, g.

3.39 vs 980. Higher latitudes may be less, I am guessing.

So are you suggesting we can feel the earth spinning?

I feel the sky tumblin’ down, a-tumblin’ down

No, just giving a quantification to why you can’t, even at the equator. At least while you are not drinking.

I sent a text to my kids with a selfhey in my new job/office. My D2 says “You are so handsome!” Good work day!

I’ve debated whether to share this or not…
but I’m so beside myself with pride that I feel compelled to do so. ← clicky clicky

commentary, credits, and text

Commentary by the choir director: “In the song, the poet is reminiscing about their life and the friends and the family that they remember in their past and their youth and then we have once again this connection because when it’s all said and done we are all one family in God.”

Only in Sleep… Bethel Choir
Ēriks Ešenvalds
Text by Sara Teasdale

Only in sleep I see their faces,
Children I played with when I was a child,
Louise comes back with her brown hair braided,
Annie with ringlets warm and wild.
Only in sleep Time is forgotten—
What may have come to them, who can know?
Yet we played last night as long ago,
And the doll-house stood at the turn of the stair.
The years had not sharpened their smooth round faces,
I met their eyes and found them mild—
Do they, too, dream of me, I wonder,
And for them am I too a child?

My 6yo lost his first tooth, and not just any kid can do that!

What’s the going rate? My younger kid we bumped up to dollar coins.
