When I flicked the card, the coin dropped into the cup.

With more pennies, they dropped into the cup, but with only one penny it went flying. This could be different because of the angles of the force.

When you flick a card, it goes flying because of the force of your fingers.

Naya

When I use less force to flick the card, the pennies still go flying.

If an object is heavier then it will most likely go into a cup, because gravity pulls heavy objects down.

If I pulled a blanket from under the school, the speed will help it overcome the friction. If the school and the cloth had zero friction, you would barely need to pull at all.

Ice does not have very much friction - it's slippery.

Sadie

Are there many types of forces?

If I pull a tablecloth out from something, how does it stay there?

Isla

srwelby — 2024-01-08 19:47:57 UTC

I wonder what it would take for the penny to stay on the card? Does the penny have wax on it?

The coin will usually go in the cup when you put it in the middle.

Aidyn

The coin goes into the cup when you flick the card.

Giselle

srwelby — 2024-02-20 19:33:00 UTC

The direction the coin goes depends on how you flick it.

Belen

It was luck if the coin went into the cup or not. We would need to use some strategy or repeat the experiment a lot of times to find out if really luck or not.

Gravity is like a big hot magnet at the middle of the earth.

I don't think there is such a thing as true motion (complicated to explain...)

Sana

There is kinetic and potential motion.

Gravity + motion = |

Eli

Will gravity eventually go away or even reverse?

2024-02-23 17:24:36 UTC

Eli

Just don't flick the coin to hard

2024-02-23 17:30:46 UTC

Friction will hope fully slow you down. It dident help the magic school bus though

how did gravity start

2024-02-23 17:31:37 UTC

like did it just spawn in

2024-02-23 17:32:14 UTC

In space there is little bits of gravity.

If you push something and there's no friction it will never stop (unless it hit's something)

if you get hit by a hammer the force pushes you to the floor

This is a example of wind force a pushing force

Eli

Gravity pulls you down that's why you can't do this (stupid gravity)
