Acceleration Due to Gravity by Free Fall Apparatus
Model Number: MTM-89
The Acceleration Due to Gravity by Free Fall Apparatus from Micro Technologies is designed for experimental determination of gravitational acceleration (g) using the free fall of a steel sphere. The system incorporates an electromagnet, release switch, steel sphere, support arrangement and impact platform for use with a compatible electronic timer.
Product Specification
The Acceleration Due to Gravity by Free Fall Apparatus from Micro Technologies provides a practical method for determining the acceleration of a freely falling object under gravity. The apparatus uses an electromagnetically held steel sphere and an electronic timing arrangement to measure the time required for the sphere to fall through a known vertical distance.
The apparatus consists of an electromagnet housed in a plastic case, with suitable connections provided for connection to an external timer. A control switch is incorporated into the unit for initiating the experiment.
A heavy steel sphere is initially held by the electromagnet. When the experiment begins, operation of the switch simultaneously releases the sphere and initiates the external timing system. This synchronization helps establish a defined starting point for the free-fall measurement.
The sphere then falls vertically under the influence of gravity toward an impact platform positioned below the electromagnet. The vertical distance between the release position and impact point can be measured as required for the experiment.
When the falling sphere strikes the cork mat on the impact platform, the timer circuit is interrupted and the timing measurement stops. The recorded fall time and measured distance can then be used to determine the acceleration due to gravity.
For an object released approximately from rest, the basic relationship is:
s = ½gt²
Therefore:
g = 2s / t²
where g is acceleration due to gravity, s is the measured falling distance and t is the measured free-fall time.
The apparatus provides a direct quantitative investigation of free fall, gravitational acceleration, displacement-time relationships and uniformly accelerated motion.
Manufactured and supplied by Micro Technologies, the Free Fall Apparatus is suitable for physics laboratories, mechanics laboratories, dynamics laboratories, research facilities and other experimental environments requiring quantitative investigations of gravitational motion.

FAQs
What is the Free Fall Apparatus used for?
The apparatus is used to experimentally determine the acceleration due to gravity (g) by measuring the time taken by a steel sphere to fall through a known vertical distance.
How is the steel sphere released?
The sphere is initially held by an electromagnet. Operating the control switch releases the sphere to begin its free fall.
How is the falling time measured?
The apparatus is connected to a compatible external timer. The release action starts the timing sequence, and the sphere's impact on the platform stops the timer.
How is acceleration due to gravity calculated?
For a sphere released approximately from rest, the measured distance and time can be used with g = 2s/t² to calculate gravitational acceleration.
What stops the timer when the sphere reaches the bottom?
The sphere strikes a cork mat on the impact platform, causing the associated timer circuit to stop the measurement.
Does the apparatus include an electromagnet?
Yes. An electromagnet housed in a plastic case is provided for holding and releasing the steel sphere.
What physics concepts can be investigated?
The apparatus can be used to investigate free fall, gravitational acceleration, uniformly accelerated motion, displacement, time and equations of motion.
