fiziksel nicelik ne demek?

Fiziksel nicelik, ya da büyüklük; görüngü, gövde ya da maddenin ölçümle sayılabilen fiziksel varlığıdır.

Temel Nicelikler

Temel nicelikler, diğer nicelikleri ifade etmede temel olan niceliklerdir. Örneğin: Zaman bir temel niceliktir. Hız, zaman ile ifade edilebilir.¹ Bu yüzden zaman temel niceliktir. Uluslararası Birimler Sistemi'nce belirlenen yedi temel nicelik ve karşılık gelen SI birimleri ve boyutları aşağıda listelenmiştir.²
