BESARAN dan SATUAN• Dimensi
———
Dimensi :
• massa [M]
• waktu [T]
• gaya [M] [L] [T]⁻²
• kecepatan [L] [T]⁻¹
———
Dimensi impuls
I = F ∆t
→ [M] [L] [T]⁻² • [T]
= [M] [L] [T]⁻¹ ✔️
a. Dimensi energi kinetik
Ek = ½ m v²
→ [M] • ([L] [T]⁻¹)²
= [M] [L]² [T]⁻²
b. Dimensi momentum,
p = m v
→ [M] • [L] [T]⁻¹
= [M] [L] [T]⁻¹ ✔️
besaran yang dimensinya sama dengan impuls afalah besaran momentum.
