2. Musculoskeletal system Role in Human heart Role in Human eyes Role in Human ear Role in Human brain Outline

3. What is Musculoskeletal system? The role of physics in Musculoskeletal system ?

4. Function : Supports body structure, protects internal organs, and facilitates movement . Bones: 206 Framework providing structural support and protection. Muscles:600 Responsible for movement through contraction and relaxation . Joints:360 Connections between bones, enabling flexibility and motion .

5. The role of the physics in Musculoskeletal system Support stability Force Energy transfer This Photo by Unknown Author is licensed under CC BY-SA Newton laws play important role in it….

6. Support and stability Gravity Every thing that has mass is in the grass What you think about the Mass of the body what you think about the Weight of the body

7. According to Newton Weight on the earth for mass of 20kg W=mg W=20*9.8 W=196N Weight on the moon for mass of 20 kg W=mg W=20*1.625 W=32.5N

8. Stability of body Center of gravity Any point on the body at which all the weight of the body acts When will the body be stable When the line of gravity passes through the base body is balanced.

9. Force in the Human Body: Muscular Forces : Muscles in the human body generate force to produce movement. Muscular force is responsible for actions such as lifting, pushing, and pulling. Contact force Newton third law valid.

10. Energy transfer Law of conservation of energy Energy cannot be destroyed or created it is transfer from one shape to another Running Pushing
