Why Is Steel Marble Faster Than Plastic Marble

Hold one marble in each hand just above the surface of the liquid in each glass.

Why is steel marble faster than plastic marble.

This is due to gravity pulling everything to the ground at 9 8 m s correct. The small marble and the larger marble rolled down the ruler at basically the same speed. 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. Limestone generally ranks at around a 3 on the scale while marble falls between 3 and 4.

3 tall containers with lids e g. Watch the glasses closely. 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. Drop a marble into each container and screw the lids on firmly.

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. 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. For marble kitchen countertops however nussbaum generally recommends sticking with white marble.

Be prepared to watch the bottom to see which marble hits first. Marble and limestone lie at the opposite end of the hardness scale from granite. Air tends to make stuff fall slower especially light objects which is why the feather hits the ground last. So after one second the object.

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. For the explanation i am actually going to simplify the probl. 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. On the other hand plastic hdpe and softwood cutting boards are given good scores on maintenance and chip risk which are great for your knives but come at the expense of the durability.

Use the funnel to fill one container with water the second with oil and the third with honey. The larger marble always goes further in distance than the smaller marble.
