Gravity Laboratory Set
Product Code : SCL-PL-12345
Gravity Laboratory Set (SKU SCL-PL-12345) measures the acceleration due to gravity by timing a falling steel ball between photogates on a graduated upright. The digital timer resolves 0.1 ms, so students obtain g from real fall times instead of stopwatch estimates. It suits Class 11 physics, B.Sc. mechanics and engineering physics labs. Science Lab Supplies manufactures the set at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and quotes schools, colleges, tender contractors and distributors directly.
Specifications
A 125 cm aluminium rod stands on a 260 x 260 x 8 mm triangular base and carries a 1.2 m scale divided in millimetres. A 19.05 mm steel ball falls past one built-in and two external photogates, and the battery timer shows each interval on a 4½-digit LCD, storing up to five readings.

Applications and Experiments for the Gravity Laboratory Set
By setting the photogates at measured heights on the scale and timing the ball's fall between them, students plot distance against time squared and read g from the gradient. Using two external gates also shows the ball's speed increasing as it falls.
- Class 11 physics: motion in a straight line and free fall under gravity.
- Determining the acceleration due to gravity from s = ½gt².
- B.Sc. mechanics practicals: error analysis with repeated 0.1 ms timings.
- Engineering physics labs: kinematics and data-handling exercises.
Standard Scope of Supply
The set comprises the 125 cm aluminium rod, the 1.2 m scale, the triangular base, the 19.05 mm steel ball and the digital timer with its built-in photogate and two external photogates. The timer runs on four LR03 batteries; any optional items are listed on the quotation.
Packing, MOQ and Lead Time
A quotation can be prepared for one set or for enough for every group in a physics practical. It confirms packing, delivery time and price for that quantity, and other free-fall and timing apparatus can be added.
Registered as an exporter under an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman.

Frequently Asked Questions
How precise is the timer in the Gravity Laboratory Set?
The timer has 0.1 ms resolution and accuracy over a range of 0.0001 to 999.99 s, and it stores five measured times.
How many photogates are included?
Three: one built into the timer and two external photogates that are set along the 1.2 m scale.
Is Science Lab Supplies the manufacturer or a trader?
It is the manufacturer. The gravity set is made at the company's Ambala factory in Saha, India, and the quotation you receive comes from that factory.
What powers the timer?
It runs on 6 V DC from four LR03 batteries, so no mains socket is needed at the bench.
