विमाएं
भौतिक राशियों के व्युत्पन्न मात्रक निकालने के लिए मात्रकों पर जो घातें लगानी पड़ती हैं, उन्हें उस राशि की विमाएँ कहते हैं। यदि किसी राशि की विमाएँ लम्बाई में Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\mathbf {a}} , द्रव्यमान में Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\mathbf {b}} , समय में Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\mathbf {c}} तथा ताप में Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\mathbf {d}} हो तो उस राशि की विमाओं को निम्नलिखित प्रकार से प्रदर्शित किया जाता है—
(Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\mathbf {L}} Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\mathbf {a}} Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\mathbf {M}} Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\mathbf {b}} Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\mathbf {T}} Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\mathbf {c}} Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\mathbf {Q}} Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\mathbf {d}} )
उपर्युक्त सूत्र को इस राशि का विमीय सूत्र कहते हैं।
अदिश राशियाँ
- REDIRECTसाँचा:मुख्य
जिन भौतिक राशियों को पूर्णतः निरूपित करने के लिए केवल परिमाण की आवश्यकता होती है, दिशा की नहीं, उन्हें अदिश राशियाँ कहते हैं।
सदिश राशियाँ
- REDIRECTसाँचा:मुख्य
जिन भौतिक राशियों को पूर्णतया निरूपित करने के लिए परिमाण के साथ–साथ दिशा की भी आवश्यकता पड़ती है, उन्हें सदिश राशियाँ कहते हैं।
