PSSC Inertial Balance Experiment Kit
$62.00(Ex GST)
- Inertial balance kit demonstrates mass from oscillation frequency, clarifies mass versus weight concept.
- Fixed plate clamps to table, second overhanging plate oscillates horizontally via spring blade connection.
- Add masses to oscillating plate to change frequency, compare oscillation timing between different loads.
- Masses can sit on plate or be separately supported by cord, supports different loading approaches.
- Stopwatch timing method for oscillations, simple frequency comparison for classroom mechanics practicals.

Description
The PSSC inertial balance kit demonstrates how mass can be determined from the vibration frequency of an oscillating system, and it helps clarify the difference between mass and weight. It shows that while weight depends on gravity, the inertial property of mass can be investigated through oscillation behaviour rather than gravitational force.
The apparatus uses two plates: one plate is clamped to the table, and a second plate overhangs the table and is connected to the fixed plate by spring blades. These blades allow the overhanging plate to oscillate back and forth in the horizontal plane. Masses are placed on the oscillating plate either directly supported by the plate or separately supported by a cord. Oscillation timing is measured by stopwatch for frequency comparison between different loads.
FAQs
Q: What does an inertial balance measure in principle?
A: Mass determination from the oscillation frequency of a vibrating system.
Q: What concept does it help explain?
A: The difference between mass and weight.
Q: How does the oscillating plate move?
A: It oscillates back and forth in the horizontal plane, guided by spring blades.
Q: How are masses applied during the experiment?
A: Masses are placed on the oscillating plate, or supported separately by a cord.
Q: How is timing measured?
A: Using a stopwatch to time oscillations.
