संकल्पना:

कार्य:

  • बल आणि विस्थापनाच्या बिंदू गुणाकाराला केलेले कार्य म्हणतात.
  • कार्याचे SI एकक जूल आहे.
  • केलेले कार्य खालील प्रमाणे दिले जाते:

कार्य (W) = F.s cos θ _____(1)

जेथे,

F म्हणजे बल

s म्हणजे विस्थापन

θ म्हणजे F आणि s यांच्यातील कोन आहे.

स्पष्टीकरण:

आपल्याला माहित आहे की कार्य (W) = F.s cos θ _____(1)

∴ बल = वस्तुमान × त्वरण

बलाचे मितीय सूत्र (F) = [MLT-2]

विस्थापनाचे मितीय सूत्र (s) = [L]

समीकरण (1) मध्ये बल आणि विस्थापनाचे मूल्ये कोन दुर्लक्ष करून ठेवा,

कार्य (W) = F.s

कार्य (W) = MLT-2.L

कार्य (W) = ML2T-2

कार्याचे मितीय सूत्र (W) = [ML2T-2]
