आवेग

(अंग्रेज़ी:Impulse) बल और समयान्तराल के गुणनफल को बल का आवेग कहते हैं।

यदि किसी पिंड पर एक नियम बल 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 {F}} को 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/":): \bigtriangleup {\mathbf {t}} समान्तराल के लिए लगाया जाये, तो इस बल का आवेग 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 {F}} x 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/":): \bigtriangleup {\mathbf {t}} होगा। आवेग एक राशि है। इसकी दशा वही होगी जो बल की है।

अतः किसी पिंड को दिया गया आवेग, पिंड में उत्पन्न संवेग–परिवर्तन के बराबर होता है। अतः आवेग का मात्रक भी वही होता है जो संवेग (न्यूटन.सेकेण्ड) का है।
