Mechanics- linear and rotational motion.pptx

A brief introduction to Mechanics - linear and rotational motion

1. Mechanics

2. LINEAR MOTION

3. LINEAR DISPLACEMENT, x = ????????? LINEAR DISPLACEMENT, x = 50 m

4. LINEAR DISPLACEMENT, x LINEAR DISPLACEMENT/TIME = LINEAR VELOCITY v ,

5. ANY DIFFERENCE??????

6. UNIFORM VELOCITY 0 s 1s 20 m Velocity=20m/s 2s 20 m Velocity=20m/s

7. ACCELERATION The rate of change of velocity of an object with time 0 s 1s 10 m Velocity=10m/s 2s 20 m Velocity=20m/s NON UNIFORM VELOCITY

8. UNIFORM VELOCITY 0 s 1s 20 m Velocity=20m/s 2s 20 m Velocity=20m/s ACCELERATION=0

9. FORCE

10. INERTIA

11. INERTIA ====mass

12. ROTATION

13. ROTATIONAL MOTION ANGULAR DISPLACEMENT, θ

14. ROTATIONAL MOTION ANGULAR VELOCITY ω rate of change in angular displacement w = q t radians per second

15. rate of change in angular velocity ANGULAR ACCELERATION α α = w t

16. TORQUE

17. MOMENT OF INERTIA Inertia of a rotating body I Angular mass or Rotational inertia

18. FORCE AND TORQUE

19. Linear - Rotational linear displacement d x Angular displacement d θ velocity v angular velocity ω acceleration a angular acc. α mass m moment of inertia I p = mv L = I ω F = ma T = I α
