Experiment to measure the acceleration due to gravity: results


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

Answers to questions

  1. Was the value for ‘g’ the value you expected. If not, can you think why the value for ‘g’ is less or greater than what you expected.
  • Air resistance will impede the magnet as it falls
  • The induced emf represents electrical energy. This cannot have been created out of nothing — it is obtained at the expense of the magnet's kinetic energy.
  • Lenz’s law is another way of looking at the same thing — the induced emf always oposses the motion of the magnet — thereby slowing it down.


  • The kit (2408B) is of obvious quality, easy to setup and calibrate and the free to download software has a reasonable learning curve. Superb kit, superb support, what more can I say.

  • I have been using my 4224 PicoScope for years. I travel abroad so this has been ideal due to its physical size. Storage of waveforms on my Laptop is very easy allowing me to quickly email waveforms to my Colleagues.

  • Not many USB scopes works on Win & Mac & Linux too, so that proves me that guys from Pico really cares about us, customers. This made my decision much easier when I was looking to buy an USB scope.

  • We have been using Picoscope 6404D for quite some time, and are amazed by its accuracy and powerful emulations while working with numerous signal evaluations.

  • PicoLog TC-08: This is a very nice unit that works consistently and reliably.

  • It is a great scope. I had a weird problem - it did not work on one of my PC’s. Customer service gave me first class service. If I could give 6 stars for customer service - I would do so.

  • Perfect Partner for Development of Encoder controlled Stepper Motor Actuators. Since the included software is really stable, this type of device is a great tool for great tasks!

    Helmut Schoettner
  • A superb piece of equipment worth its weight in gold

    Nigel Clinch
  • So simple to use & beats any other I have ever used hands down.

  • Great functionality in a compact size. I really like moving the mouse pointer to a position and having the Time and Voltage display the values at that point. Calibration equipment is a breeze with that feature.
