Why Is Steel Marble Faster Than Plastic Marble

While marble is slightly harder and denser than limestone both rate very low on the mohs scale a rating used to measure the hardness of stones.

Why is steel marble faster than plastic marble.

The answer is actually a historically very important problem known as the brachistochrone problem and was one of the problems which lead to the development of calculus of variations. For the explanation i am actually going to simplify the probl. Hold one marble in each hand just above the surface of the liquid in each glass. The larger marble always goes further in distance than the smaller marble.

Be prepared to watch the bottom to see which marble hits first. Glass cutting boards are very hard almost as hard as steel and will not score which is why these boards are notorious for dulling even the best of knives. Drop a marble into each container and screw the lids on firmly. Marble and limestone lie at the opposite end of the hardness scale from granite.

So after one second the object. When an object is in free fall gravity increases its velocity by 9 8 m s with every passing second. Air tends to make stuff fall slower especially light objects which is why the feather hits the ground last. This is why the old gravestones of the midwest are barely legible because acid rain created by factory pollution has dissolved a lot of the calcite in the limestone and marble gravestones.

Did the marble travel faster as it went farther down the slope. Since tennis balls and basketballs are quite heavy at least compared to feathers we don t easily notice the effect of air resistance on these although it s still there. Use the funnel to fill one container with water the second with oil and the third with honey. This is due to gravity pulling everything to the ground at 9 8 m s correct.

For marble kitchen countertops however nussbaum generally recommends sticking with white marble. Clear plastic tubes or glass jars plastic tubes used to store buttons are ideal if the holes in the lids are sealed what to do. Watch the glasses closely. Because acid etching leaves a whitish mark it is much more noticeable on colored marble than on.

As the elevation of the ramp increases so does the average speed of the marble right. Limestone generally ranks at around a 3 on the scale while marble falls between 3 and 4.
