Mavrix Crater Ball, High Density PU Bouncy ball

Product Information

I think that the answer is due to the properties of the landing material. The sand was very good at stopping balls dropped vertically or from a steep angle, but the retardation of balls at a shallow angle was much less. Only a frictional force was available to stop the smooth ball. This meant that the ball skipped across the sand, further than expected – as shown on the graph above.

Drop the impact object from this height and use the stopwatch to time the descent. The stopwatch must be stopped once the impact object has hit the flour/cocoa. A single-layer transition-metal dichalcogenide on top of a silver film displays strong light–matter coupling without the need for nanostructures or microcavities.The second graph also seems to show a linear relationship, but once again a single anomalous result is apparent. The large depth for the drop from 50cm suggests that the sand might have been less compact than usual, as this would have meant that the ball penetrated deeper than usual, with the grains being further apart. Durian and his colleagues dropped balls of many different materials and densities–from silicone rubber to ceramic–into materials such as sand, popcorn, and ice cream sprinkles. But the materials didn’t matter much; the depth was mainly affected by the density and diameter of the ball and the height from which it was dropped. Their crater diameters followed the “energy to the 1/4 power” rule of thumb, but the depth didn’t depend on energy in a simple way. This result doesn’t contradict the work of de Bruyn’s team because the UCLA researchers defined depth by measuring to the bottom of the buried ball, which was deeper than the bottom of the crater. Barringer Crater ( also known as Meteor Crater ) in Arizona was created instantly when a 50-meter (164-foot), 150,000-ton meteorite slammed into the desert around 50,000 years ago. Using the formula below, calculate the density of each impact object and note your results on the spreadsheet: The pressurised suits severely restricted movement, and due to their helmet's visors they struggled to even see their feet.

Scale this project up! Do you have access to a sandbox, a shovel, and some dirt? Try the project outside. Create a large pile of loose material: dirt covered with a layer of sand (similar to the flour covered with cocoa powder). Ask an adult for help dropping a larger ball, like a basketball, from a higher location (like standing on a ladder). The issue is that there are multiple crater scaling laws, each with different assumptions, as Horedt & Neukem (1984) show (title of paper is Comparison of six crater-scaling laws). Cardboard box; it should be larger than a shoebox and fairly deep. Something like a small moving box would be perfect. Another linear relationship – this time it is looser though. This could be due to the masses of the balls being slightly different. It was very difficult to find balls with similar masses – it would have been near impossible to find so many balls with identical masses.This first experiment is a fairly simple one, however it is necessary – it will serve as a test for the equipment and methods used. The next step is to model the ball as a projectile, to investigate further the independence of horizontal and vertical components of motion. When making your craters, you may have noticed that the higher you drop the ball from, the greater its velocity (or speed) at impact. The greater an object’s velocity, the larger the impact crater. John de Bruyn, of Memorial University of Newfoundland in St. John’s, Canada, says that his group wasn’t originally interested in craters at all, but was considering the crown-shaped splash that appears when an object is dropped into a liquid. “We had just acquired a high-speed camera, and my post-doc was interested in seeing crown splashes in sand.” It turned out that sand doesn’t splash like a liquid, but the resulting pits looked a lot like craters on the moon.

The height from which a ball (a simple model of an asteroid or meteor) is dropped and the diameter of its impact crater. Nanotechnology in action The challenges and opportunities of turning advances in nanotechnology into commercial products After carrying out the above activity, hand each student a worksheet. Ask them to answer and discuss the questions provided. Fill the pan about 2 cm deep with flour, lightly sprinkle the drinking chocolate to cover the entire surface. By changing the vertical height, the ball’s energy would by affected. It would be sensible to predict that more energy would make for longer, deeper craters.

Volcanic material in some summitcraters is near the surface, but not visible. Although Mount Fuji is an active volcano and magma and gases sit below the summitcrater, the risk of an eruption is very low. Mount Fuji, Japan’s highest mountain, is one of the most popular places in the country to hike. And not only did he manage to find the second ball, which had not been seen in 50 years, he also worked out how far it actually went.

In this activity, objects of differing densities and sizes (marbles, ball bearings and golf balls) will be dropped from a known height onto a surface of flour and cocoa. Once dropped, the kinetic energy of these objects will blast a crater into the surface, sending out rays (ejecta rays) around the object. Students will note the shape/extent of these rays, and once the object is removed from the crater, they can also measure its diameter. Results of this investigation can be presented graphically or verbally, and conclusions drawn regarding the nature of impact craters on Earth. Any improvements that can be made on the experiment can then be discussed. Full Description Astronomers think big! They want to understand the entire universe—the nature of the Sun, Moon, planets, stars, galaxies, and everything in between. An astronomer's work can be pure science—gathering and analyzing data from instruments and creating theories about the nature of cosmic objects—or the work can be applied to practical problems in space flight and navigation, or satellite communications.

Figure 1 from the paper, reproduced below, shows a plot of crater diameter versus impactor mass for the 6 different equations at a constant velocity (10 km/s) for solid-solid (solid lines) and ice-ice impacts (dashed lines). This graph is very pleasing, as both the crater diameter and depth appear to have good linear relationships with the mass of the ball. I would challenge any club golfer to go to their local course and try to hit a six-iron, one-handed, with a one-quarter swing out of an unraked bunker. Table 1.
