G1-18: PENDULUM WITH FORCE SCALE

Additional Info

  • ID Code: G1-18
  • Purpose: Show the tension in the string exerted by a swinging pendulum.
  • Description: The spring scale reads the tension in the string as the pendulum swings, about 25 Newtons at the center and 19 Newtons at the ends of the swing with a bob mass of 1.1 kG. In this setup: F (center) = mg + mrw^2 = mg (3 - 2 cos a) F(end) = mg cos a where by conservation of energy m v^2 /2 = m r^2 w^2 /2 = mgr (1 - cos a) m r w^2 = 2mg ( 1 - cos a)
