Marble motion!

Guiding questions:
Does the mass of a marble affect how it moves?
When adding a force, how does it change the motion?

Hypothesis:I think that the bigger objects would be harder to move because it has a bigger mass and the smaller objects to move easyer.

For the marble, on the first test it bounced allot off of the ruler beside it but it still went off the table 128cm+. On the second test it only bounced once and went to 124 cm!
For the small foam ball, the first test we did the ball went off of the table at 104cm, but went off track at about 75cm. But when we did the second test, the ball was swiveling a little bit but not to much to throw it off course. In the end, it still went all the way off of the table.
For the pingpong ball, on both tests both of then went off of the table at 120cm+. But it took a much lesser force than it took for the big Marble to move.
As you can see that in this test the golf ball didn't get to the end, but it got almost to the end. It also took a much harder force to make it move than just one regular breath.
For the big marble you can see that the first one it went rite off of the table but it took a much harder force to get it to move forwards on both sides.
Hear you can see that the big fome ball left the table at 33 cm with the normal breath on one side, but on the other side, we had the same breath but this time it went strait 128+!

Data analyses:
While me and Clare were measuring the distance that the objects traveled, we saw that most of the bigger objects that had more mass, were harder to make them move. When we were looking at the pingpong ball, and at the big marble, we saw that the big marble was harder to move but the pingpong ball was bigger than the big marble. So then I thought about it. It doesn't mater how much mass it has, it matters how much matter it has in it! In translation into more simple words, it doesn't rely mater how big the object is, it matters how lite and heavy it is.

Conclusion:
The guiding questions and answers:
1. Does the mass of a marble affect how it moves? I think that the mass of a marble DOES affect how it moves. When me and Clare tested the bigger and smaller objects, and in the end, we found that smaller objects move further and faster than the bigger objects. Down below you can see our results. 2. When adding a force, how does it change the motion? When you don't add any force to an object, it just stands still, but when you apply force, it starts to move. For an example: in this lab that we are doing rite now, if i have a marble and I put it on the table and blow on it with a straw, it moves. Rite? But when i put a object that has more mass, it still moves like the little marble did! Now, why is that? When you compare two objects like a little marble, and a pingpong ball, they look very different, but when you actually blow on both of them you will find the result! They both move with the same amount of force! Why is that? Well, it rely doesn't mater how much mass the object has, it matters how much matter it has!
Further inquire:
My questions:
  1. If I had a long clear empty tube about the size of a regular marble and placed it somewhere on flat ground and slid the little marble in it and let it go, how far would it go?
  2. Would it go further than the table test? Or would it go the same as the table test/or smaller?
  3. Does adding more/or less force to the object, affect the motion of it?
  4. Does the type of Matter affect the motion of an object?

  1. In your data analysis, do you mean that it doesn't matter the mass, but the density of the object? Which is the amount of matter in a given volume, remember? Great job on this post!
