Taking MATLAB as the experimental platform, the detection and recongnition method of steel ball surface defect is put forward. With the method, we could determine whether there are surface defects or not, and identify the types of defects. The process of detection and recognition is as follows: Firstly, two-time wavelet de-noising treatment of the steel ball image is achieved by …

When a cricket ball is dropped from a height of 2.0 m onto a heavy steel plate, it bounces to a height somewhere between 0.56 m and 0.76 m. Cricket balls are a lot less bouncy that tennis balls and the permitted range of possible bounce heights is larger. A useful way of specifying the bounce is to take the ratio of the bounce speed to the ...

Drilled balls are great to make pendulum bobs or for doing impact experiments. This 3/4" diameter steel ball has a 3mm hole drilled completely thru its axis with chrome finish.

The ball did not seem to bounce as high when she practiced dribbling at home. She was very surprised because it was the same ball that she had used earlier to practice dribbling in the school gym. This made ... The Scientific Method: An Investigation of …

Also, by giving you only the options "same" and "different", the question setter managed to fool you again, because constant speed means zero net force. If the question had asked you to list the forces on each object, you might have done something like this: M: Net force = 0, Gravity = Mg, Drag = -Mg. 2M: Net force = 0, Gravity = 2Mg, Drag = -2Mg.

We wanted to create something that allows kids and adults to construct their own large-scale rolling ball sculptures, and to have fun building and re-building new and different creations. In 2017, we ran a successful Kickstarter Campaign to fund the initial orders of Wonderstructs, and in 2018, we delivered those first kits to our backers.
