Falling physics that Every Climber Needs to know
-
0:02 - 0:04רשום קילוניוטון..
-
0:05 - 0:07ואחרי הסרטון הזה
-
0:07 - 0:09יהיה לך הרבה יותר הבנה,
-
0:09 - 0:13מאשר 99% מהמטפסים,
-
0:13 - 0:16על מה בעצם המשמעות של קילוניוטון
-
0:16 - 0:20ואילו כוחות מעורבים בנפילות בזמן טיפוס.
-
0:20 - 0:24ואז אסביר למה נפילות גדולות
-
0:24 - 0:27הן לרוב רכות יותר מנפילות קטנות.
-
0:27 - 0:30אבל ראשית, נבין קודם מה זה כוח.
-
0:30 - 0:33אני אוהב להשתעשע עם העוקבים שלי באינסטגרם
-
0:33 - 0:36אז שאלתי אותם:
"מה עולה לכם לראש -
0:36 - 0:39כשאתם שומעים את המילה כוח"
-
0:39 - 0:40חצי מהאנשים ענו
-
0:40 - 0:43שזה קשור 'למלחמת הכוכבים'
-
0:43 - 0:45מתקבל.
-
0:45 - 0:46ורגע לפני שנסיק
-
0:46 - 0:51שחצי מהעוקבים שלי הם ממש חכמים,
-
0:51 - 0:54אני חייב לומר שהרוב לא הגיבו בכלל.
-
0:54 - 0:55אז דמיינו משהו כזה..
-
0:55 - 0:58מה זה כוח?
-
0:58 - 1:01[שגיאה]
-
1:01 - 1:03אוקי.. ואלו שרצו להישמע חכמים
-
1:03 - 1:07אמרו שכוח זה מסה כפול תאוצה
-
1:07 - 1:10שזו הנוסחה שניוטון. הבחור הזה.
-
1:10 - 1:11ניסח
-
1:11 - 1:12[ניוטון]: בויה!
-
1:12 - 1:14וזו הסיבה שאנחנו מודדים כוח בניוטונים
-
1:14 - 1:17עבורי זה קצת משעשע אם חושבים על כך..
-
1:17 - 1:19דמיינו את ניוטון
-
1:19 - 1:21
-
1:22 - 1:25אז אנחנו מודדים מסה בקילוגרמים,
-
1:28 - 1:33ומודדים תאוצה במטר לשניה
