Our cycloid pendulum is composed of a commercial teaching material of a simple pendulum and a pair of cycloid shaped walls. Theoretically the period of the cycloid pendulum is constant, which is determined simply using the distance between the fulcrum of the pendulum and the center of gravity of the weight. However, our measured period, which has an accuracy of 1 μs, increased as the angular amplitude increased. The reasons for this discrepancy were mainly the air resistance of the weight and the deflection of the thread of the pendulum. Then, we changed the kind of weight and the materials of the thread and again measured the dependence of the angular amplitude on the periods of the cycloid pendulum. As a result, the periods were almost constant when we used the glass marble as a weight and the leveling string as a thread even if we increased the angular amplitude.","subitem_description_type":"Other"}]},"item_120_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_120_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_120_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24561/00019087","subitem_identifier_reg_type":"JaLC"}]},"item_120_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"埼玉大学教育学部"}]},"item_120_publisher_12":{"attribute_name":"出版者名（別言語）","attribute_value_mlt":[{"subitem_publisher":"Faculty of Education, Saitama University"}]},"item_120_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18815146","subitem_source_identifier_type":"ISSN"}]},"item_120_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版]"}]},"item_120_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"SAITO, Aya"},{"subitem_text_value":"NAMIKI, Toshiki"},{"subitem_text_value":"KONDO, Hitoshi"},{"subitem_text_value":"OHMUKAI, Ryuzo"}]},"item_120_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"KY-AA12318206-6902-32"}]},"item_120_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学教育学部自然科学講座理科分野"},{"subitem_text_value":"埼玉大学大学院教育学研究科"},{"subitem_text_value":"埼玉大学教育学部自然科学講座理科分野"},{"subitem_text_value":"埼玉大学教育学部自然科学講座理科分野"}]},"item_120_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Faculty of Education, Saitama University"},{"subitem_text_value":"Graduate School of Education, Saitama University"},{"subitem_text_value":"Faculty of Education, Saitama University"},{"subitem_text_value":"Faculty of Education, Saitama University"}]},"item_120_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2020"}]},"item_120_version_type_28":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"齋藤, 彩"},{"creatorName":"サイトウ, アヤ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"並木, 俊樹"},{"creatorName":"ナミキ, トシキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"近藤, 一史"},{"creatorName":"コンドウ, ヒトシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"大向, 隆三"},{"creatorName":"オオムカイ, リュウゾウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-10-14"}],"displaytype":"detail","filename":"KY-AA12318206-6902-32.pdf","filesize":[{"value":"979.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KY-AA12318206-6902-32.pdf","url":"https://sucra.repo.nii.ac.jp/record/19118/files/KY-AA12318206-6902-32.pdf"},"version_id":"a6729f00-4df2-4006-b66c-9cadc45c2dbc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"単振り子","subitem_subject_scheme":"Other"},{"subitem_subject":"サイクロイド振り子","subitem_subject_scheme":"Other"},{"subitem_subject":"周期測定","subitem_subject_scheme":"Other"},{"subitem_subject":"コンピュータ計測","subitem_subject_scheme":"Other"},{"subitem_subject":"simple pendulum","subitem_subject_scheme":"Other"},{"subitem_subject":"cycloid pendulum","subitem_subject_scheme":"Other"},{"subitem_subject":"precise period","subitem_subject_scheme":"Other"},{"subitem_subject":"computer measurement","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"小学校教材で製作したサイクロイド振り子の周期精密測定<数学・自然科学>","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"小学校教材で製作したサイクロイド振り子の周期精密測定<数学・自然科学>"}]},"item_type_id":"120","owner":"3","path":["969"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-10-14"},"publish_date":"2020-10-14","publish_status":"0","recid":"19118","relation_version_is_last":true,"title":["小学校教材で製作したサイクロイド振り子の周期精密測定<数学・自然科学>"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T16:34:54.439956+00:00"}
