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]
