Guide questions:
1. How do the speed and angle of the marble rolled on the cloth affect the path and movement of the rolling marble?
2. What have you observed to the movement of the marble rolled when the heavy stone is replaced?
3.What have you observed to the movement of the objects replacing the marble when rolled?
4. How does the tablecloth activity demonstrate the effect of gravity on the movement of objects?
Answer:
1. The marble started accerelating the angle didn't change and if you flick the marble it will become fast and the cloth won't affect the marble.
2. The marble collided with the heavy stone the marble going faster after colliding the marble reflected in the other direction left or right not going forward and a bit of speed reduction.
3. The marble got a bit of speed of reduction on the heavy stone and reflected not making it go forward making it go left and right and the cloth it didn't do much if the table is very long it might stop.
4. The smaller the object the faster it is the heavier the object how slow it is more mass more gravity the cloth has some friction on it but the marble doesn't it's smooth so it won't affect to it that much.
