why did the yarn ball always go off track?
does the size of the ball create more friction?
Why did the marble go the farthest?

# data[].attributes.body
Do the speed differences depend on the weight?

1.Does the carpet have more or less friction than the tile?

2.to the balls roll difrentley on carpet and tile?

3.wich one goes faster and slower on tile and carpet?

# data[].attributes.body
i think its about how much mass their is in eah object

# data[].attributes.body
does the mass of a ball affect the speed of it

# data[].attributes.body
does the ball have gravetational potebtial energy

# data[].attributes.body
if the ball hit on a wall, the ball goes back.why does ball go back even wall is not pushing the ball?    q0o0p

# data[].attributes.body
I wonder why the ball goes fast at the beginning and slow at the end?

# data[].attributes.body
did mrs sanchez always have the same force

# data[].attributes.body
how hard did the teacher roll???

# data[].attributes.body
How fast are the balls?

# data[].attributes.body
Why does different material affect the balls force?

# data[].attributes.body
do different materials make a ball faster

# data[].attributes.body
Why did the yarn turn right ? how did the marble pick up speed ? How much force did Ms.Sanchez use for the plastic ball

# data[].attributes.body
dose it matter what material its made out of?
how come the marble is faster?
dose it matter what shape the ball is to go faster and slower?

# data[].attributes.body
How marbol go faster?

# data[].attributes.body
will the ball of twine string always come out

# data[].attributes.body
How much potential energy is there right before rolling a ball? What differences are there with how much friction there is with the yarn ball, plastic ball, and marble? What are the speed differences between the three balls?

# data[].attributes.body
1.why did the yarn keep going to the side?
2.which of the balls was the fastest?
3.which floor had more friction

How Does a ball roll differently on different surfaces

# data[].attributes.body
how does the air not stop it?

# data[].attributes.body
witch one goes faster

# data[].attributes.body
Dose the plastic ball roll faster than the yarn ball?

# data[].attributes.body
how much potential energy does it use

# data[].attributes.body
do different balls roll faster on different surfaces

# data[].attributes.body
How much friction was there?
How fast was it going?
How much force did Mrs. Sanchez use?

# data[].attributes.body
Which surface had more friction? How fast did the marble roll? How much force did mrs.Sanchez put into the balls?

# data[].attributes.body
Does a ball's size affect its speed

# data[].attributes.body
I wonder if the speed of the yarn is fast as the plastic ball?

# data[].attributes.body
why does the ball of yarn release its string when it rolls
