Deluxe Free Fall Apparatus with Pendulum

• An essential piece of equipment in basic dynamics studies.
  
• Can be used for qualitative and quantitative study of free falling bodies for demonstration experiments (acceleration due to gravity.)
  
• Unit is mainly made of an aluminum alloy; equipped with a scale.
  
• Consist of an electromagnetic device that holds the ball in place, a digital timer to record all statistics of the experiment, 3 moveable photogates (photo sensors) in the middle part of the frame, and a receiving net, which is fixed on the cast-iron base and tripod at the lower end of the vertical rod.
  
• Basic Concept: A steel ball is held in place with and electromagnet. The timer is equipped with a button to release the power holding the ball, allowing the free fall motion. Acceleration of the free fall motion of the steel ball is captured by 3 moveable photogates & recorded by the timer.
  
• The three photogates on the vertical rod can be freely moved to any position and can be easily read against the bright yellow scale
  
• The vertical rod is fixed on a solid tripod base and can be easily adjusted to true vertical by means of the leveling bolts on the tripod base and the included plumbline
  
• Overall height of instrument: 5.25 ft (1.6m)
  
• Overall height of experiment: 4.9 ft (1.5m)
  
• Power of electromagnet: 6 volt
  
• Diameter of steel ball: 18 mm
  
• Relative errors on measuring g: (the acceleration of free fall) 2%
  
• Complete set includes Free Fall apparatus and accessories, digital timer, electromagnetic device, 3 photogates, 18mm steel ball, plumbline, pendulum, all cables and plugs, and instructions.
  
• Supplied with photogates, but with out timer.

Measurements are approximate.
