High speed and high resolution. Breakthrough ADC technology switches from 8 to 16 bits in the same oscilloscope.
s = ut + ½ at2
For the magnet falling to the first coil, where t is the time taken to reach the first coil.
0.145 = 0 + ½ at12
For the magnet falling from the start position to the second coil, where t again is the time taken to reach the first coil.
0.675 = 0 + ½ a(0.2026 + t)2
Solving the two equations for ‘a’ will arrive at a value for the acceleration due to gravity (g).
a = 9.5 m/s2
