Apparatus for Determining "G" During the Free Fall of Bodies.
Product Code : SCL-PL-11804
Apparatus for Determining "G" During the Free Fall of Bodies (SKU SCL-PL-11804) measures the acceleration due to gravity by timing a steel ball as it drops through a measured height. A magnet release and a contact plate start and stop the timing, so students work from repeatable readings rather than reaction times. It is manufactured by Science Lab Supplies in the HSIIDC Industrial Area at Plot 448, Saha, Ambala, India, for direct supply to schools, colleges, tender contractors and distributors.
Specifications
A micro-magnet holds the ball at its start position above three contact pins. These pins fix the start point and act as a switch that opens when the ball is released, starting the digital stopwatch. The ball stops the timer when it strikes the contact plate below, which also holds it so it does not bounce.

Applications and Experiments for the g by Free Fall Apparatus
The apparatus is used to find g from the fall time t over a measured height h, using h = ½gt². Repeating the drop at several heights and plotting h against t² gives a straight line whose slope is g/2, a standard exercise in school and first-year college mechanics.
- NCERT Class 9 science (Gravitation): measuring the acceleration due to gravity.
- NCERT Class 11 physics (Motion in a Straight Line): equations of uniformly accelerated motion.
- Graphing h against t² and discussing experimental error in a practical record.
- Diploma and first-year undergraduate mechanics labs: determination of g by free fall.
Standard Scope of Supply
The set comprises the release mechanism with micro-magnet and three contact pins, the bottom contact plate, a digital stopwatch, a 1.5 m / 2 m tape measure for the drop height, and three steel balls. Any optional items requested are shown separately on the quotation.

Frequently Asked Questions
How does the apparatus start and stop the timer?
Releasing the ball opens the switch formed by the three contact pins, which starts the stopwatch; the ball stops it on hitting the contact plate at the bottom.
What is included in the set?
The release mechanism, contact plate, a digital stopwatch, a 1.5 m / 2 m tape measure and three steel balls.
Is Science Lab Supplies the manufacturer or a trader?
Manufacturer. The apparatus is assembled in Science Lab Supplies' own plant in Saha, Ambala, India, and your quotation comes straight from that plant.
Why does the ball not bounce at the bottom?
The contact plate holds the ball firmly when it lands, so it stays in place after the timer stops and can be picked up for the next drop.
