Free fall
Installation for studying free fall: an electromagnetic holder, a photogate and a stand with a scale allow you to measure g using several methods.
The apparatus consists of a vertical stand with a measuring scale, an electromagnetic holder, a photoelectric sensor, a receiving frame and a steel ball. The electromagnet releases the ball without an initial push, and the photogate records the time of the fall. Four experiments are provided: checking the uniformly accelerated nature of free fall, determining gravitational acceleration from height and time, a two-photogate method that eliminates error due to residual magnetization, and studying the fall using the method of stroboscopic photography with an external strobe and camera. The device is intended for demonstrations on kinematics in a physics course.
- 1.Vertical stand with a measuring scale on the base - 1 pc.
- 2.Electromagnetic ball holder - 1 pc.
- 3.Photoelectric sensor (photogate) - 2 pcs.
- 4.Ball-catching frame - 1 pc.
- 5.Steel ball - 1 pc.
- Testing uniformly accelerated free fall: distance travelled is proportional to time squared
- Measurement of gravitational acceleration by height and time of fall (single photogate method, g = 2h/t²)
- Measuring the acceleration of gravity by the method of two photogates: movement with a non-zero initial speed - the error from the residual magnetization of the electromagnet is eliminated
- Studying free fall using stroboscopic photography (with an external strobe light and camera)
