Product Material – High-grade metal with anti-corrosive coating

Grade – Laboratory/educational grade

Application – Measurement of gravitational acceleration (g) via free-fall method

Product Overview

The ‘g’ by Free Fall Method Setup is a meticulously designed apparatus for precise measurement of gravitational acceleration in controlled laboratory environments. Constructed from high-grade metal with an anti-corrosive finish, this setup ensures durability and long-term reliability, even under frequent use. The mechanism employs a free-fall technique, where an object is dropped from a fixed height, and the time taken to cover the distance is recorded with minimal air resistance interference. The setup includes a robust release mechanism for consistent drops, a high-precision timer (compatible with external digital timers), and an adjustable height stand to accommodate varying experimental requirements. The vertical guide ensures the falling object follows a straight path, eliminating lateral deviations that could compromise accuracy. Ideal for educational institutions, research labs, and physics demonstrations, this apparatus adheres to standard lab safety protocols while delivering repeatable, high-accuracy results. Its user-friendly design allows for quick assembly and disassembly, making it convenient for both temporary setups and permanent installations. The included instruction manual provides clear guidelines for calibration and operation, ensuring seamless integration into existing lab workflows.

FAQs

1. How does the free-fall method ensure accurate measurement of ‘g’?

The setup minimizes air resistance and external interferences by using a streamlined falling object and a vertical guide. The timer records the exact fall duration, and gravitational acceleration is calculated using the formula g = 2h/t², where ‘h’ is the height and ‘t’ is the time taken.

2. Is this apparatus compatible with digital timers or data loggers?

Yes, the setup includes connectivity ports for external digital timers or data loggers. Ensure the timer has a precision of at least 0.001 seconds for optimal accuracy. Most standard lab timers with a 5V or 12V input are compatible.

3. What alternatives exist for measuring ‘g’ if this setup is unavailable?

Alternatives include the simple pendulum method, Atwood’s machine, or inclined plane experiments. However, the free-fall method is preferred for its simplicity and minimal friction-related errors, provided the setup height is sufficient (typically 1–2 meters).

4. How should the apparatus be stored to prevent damage or calibration issues?

Store the setup in a dry, dust-free environment with the components disassembled. Keep the metal parts lightly oiled to prevent corrosion, and avoid exposing the timer or electronic connections to moisture. Store the falling object separately to prevent deformation.

5. Can this setup be used for measuring acceleration due to gravity in non-standard conditions, like high altitudes?

While the apparatus is designed for standard lab conditions, it can be used at high altitudes with adjustments. However, air density changes may introduce minor errors. For high-precision results in such environments, consider using a vacuum tube setup or applying atmospheric correction factors.
