Gravity Lab Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12545
Jlab Export is a leading Gravity Lab Manufacturer,and suppliers in India
Gravity Lab (code EL-PL-12545) is a free-fall apparatus for measuring the acceleration due to gravity: a ball dropped from a release clamp lands on a base unit with a built-in vibration sensor, and a millisecond timer records the fall. Two ball bearings, a ring stand, a swivel clamp holder, a 5 V DC power supply and instructions complete the set, which JLab makes in Ambala, India.

Timing a Fall
With the release clamp and the base unit’s vibration sensor connected to the timer, the display gives the time t taken to fall a measured height h. For a ball released from rest, h = ½gt², so g = 2h/t². Repeating the drop at several heights and plotting h against t² gives a straight line of gradient g/2, which averages out timing scatter. Dropping the 12 mm and 8 mm balls from the same height shows that the fall time hardly depends on the size of the ball.
Timer Modes and Resolution
A single switch selects the mode: in the first, gate 1 both starts and stops the count; in the second, gate 1 starts it and gate 2 stops it. Times up to 10 seconds are shown to the millisecond, and beyond that the display auto-ranges up to 9999 s with correspondingly coarser resolution.
