  • 2. Standar Kompetensi: Menerapkan konsep dan prinsip dasar kinematika dan dinamika benda titik Next
  • 3. Kompetensi Dasar: Next Menerapkan Hukum Newton sebagai prinsip dasar dinamika untuk gerak lurus, gerak vertikal, dan gerak melingkar beraturan
  • 4. Indikator : Menerapkan Hukum Newton pada gerak Vertikal Next
  • 5. A. KE ATAS B. KE BAWAH C. JATUH BEBAS PENUTUP Presentasi Koputer dalam Pembelajaran Fisika
  • 6. GERAK VERTIKAL KE ATAS PERNAHKAH ANDA MELEMPAR SEBUAH BOLA KE ATAS ? V BISA ANDA JELASKAN BAGAIMANA BOLA TERSEBUT BISA NAIK KE ATAS DAN KEMUDIAN BALIK LAGI KE PERMUKAAN BUMI ? NEXT
  • 7.  MATERI Agar benda dapat bergerak ke atas maka benda harus mempunyai Kecepatan awal, pada saat benda berada di titik puncak kecepatan benda pada saat itu nol sehingga bola jatuh lagi ke permukaan bumi akibat adanya gaya Gravitasi Rumus : a) Vt=vo-gt b) ht=vot-½ gt2 c) vt2=vo2-2gh NEXT
  • 8. Keterangan rumus : Vo = kecepatan awal (m/s) Vt = kecepatan pada saat t (m/s) t = waktu benda bergerak (s) g = percepatan gravitasi (m/s2) h = panjang lintasan benda bergerak (m) NEXT
  • 9. 1. Sebuah bola dilempar ke atas dengan kecepatan awal 20 m/s, ketinggian maksimum yang dicapai adalah ……m Penyelesaian: diketahui: Vo= 20 m/s Vt2=Vo2-2gh h = Vo2/2g = ( 202 )/ 2.10 = 20 m g = 10 m/s2 ditanya : h ? jawab: Pada saat benda dititik tertinggi, kecepatan benda nol (vt = 0 ) NEXT
  • 10. 1. Sebuah bola dilempar ke atas dengan kecepatan awal 20 m/s, Maka waktu yang digunakan untuk mencapai titik tertinggi adalah … sekon. 2. Benda dilempar dengan kecepatan tertentu sehingga mencapai tinggi maksimum 80 m. Besarnya kecepatan awal benda adalah … m/s. BACK MENU
  • 11. g v DASAR TEORI  Gerak vertikal ke bawah terjadi jika sebuah benda dari ketinggian tertentu dilepas dengan kecepatan awal Rumus: a) Vt=vo+gt b) ht=vo t+½ gt2 c) vt2= vo2+2gh NEXT
  • 12. CONTOH SOAL :  Sebuah benda dilempar lurus ke bawah dengan kecepatan 10 m/s dari atas pohon dengan ketinggian 30 meter. Berapa besar kecepatan benda setelah 2 sekon dilempar! Penyelesaian: Diketahui: ditanyakan:  Vo= 10 m/s Vt ?  h = 30 m Jawab :  t =2s Vt = Vo + g.t = 10 + 10.2 = 30 m/s NEXT

Kelereng dilemparkan ke bawah dari ketinggian 20 meter dengan kecepatan awaltertentu. Jika waktu yang diperlukan benda sampai di tanah 4 sekon, hitunglah kecepatan awalnya. BACK MENU
  • 14. JATUH BEBAS DASAR TEORI Gerak jatuh bebas dapat terjadi jika benda dijatuhkan dari ketinggian tertentu tanpa kecepatan awal atau Vo=0, Rumus: a) vt= gt b) ht=½ gt2 c) vt2= 2gh NEXT Vo=0
  • 15. PERNAHKAH SAUDARA MENDENGAR BERITA ORANG TERJUN DARI LANTAI TERTINGGI DI SEBUAH GEDUNG APARTEMENT ??? ATAU PERNAH MELIHATNYA LANGSUNG ?? FENOMENA APAKAH ITU ??? NEXT
  • 16. NEXT
  • 17. Ketiga kasus tersebut merupakan GERAK JATUH BEBAS NEXT
  • 18. CONTOH SOAL :  Sebuah bola basket dijatuhkan dari ketinggian 20 meter tanpa kecepatan awal. Hitunglah waktu benda sampai di tanah! Penyelesaian: diketahui: ditanyakan: h = 10 m t? Vt ? g = 10 m/s2 jawab : h = ½ gt2 Vt= g.t t = √ (2h/g) = 10. 2 t = √(2.20/10) = 20 m/s t = 2 sekon NEXT
  • 19. LATIHAN Sebuah bola dijatuhkan dari ketinggian tertentu. Jika kecepatan benda saat mencapai tanah 40 m/s dan nilai percepatan gravitasi bumi 10 m/s2 hitunglah: a. Waktu benda selama di udara b. Kecepatan benda pada detik ke 2 s, 3s c. Tinggi benda saat dijatuhkan BACK MENU
