Mass is one of the fundamental physical quantities in physics. It describes the amount of matter contained in an object, manifested mainly in two aspects: inertia and gravity. The greater the mass, the greater the inertia and gravity. Objects with equal mass share the same inertia and gravity, so we can use a balance to measure object mass.
The beam balance is the most commonly used mass measuring tool for physics experiments in primary and secondary schools, and it is also an excellent medium to understand the principle of lever equilibrium. However, physical balances suffer from easy equipment wear, lost weights, limited classroom practice time and other issues. This application is designed to solve these pain points, letting every learner own a "portable physics laboratory".
This program is a balance experiment simulator. It faithfully restores the operating principle of the beam balance and the complete weighing workflow. Without physical lab equipment, you can practice weight combination and vernier reading anytime and anywhere, intuitively understand lever equilibrium principle, and make physics experiment learning more intuitive and efficient.
Basic principle of mass measurement with balance: Place an object of unknown mass on one pan of the balance and known weights on the other pan. When the balance levels out, masses on both sides are equal.
Mass of measured object = Sum of mass of all weights on the pan + reading from the sliding vernier on the scale.
This program is suitable for primary and secondary physics learners for independent practice, helping them consolidate balance operation points after class. It is also suitable for physics teachers for classroom demonstration, visualizing abstract mass measurement and lever principles. Naturally, it also fits enthusiasts of physics experiments for casual practice in spare time.
Built-in three test objects: cherry, ring, diamond, covering different weight ranges for step-by-step practice. You can practice weighing gradually from light to heavy and master weight selection strategies for different magnitude levels.
Offers 5 standard weights: 1g, 2g, 5g, 10g, 20g to standardize training for weight selection and combination logic. Repeated practice of the "from large to small, progressive approximation" weight adding strategy builds standardized and rigorous experimental operation habits.
Equipped with high-precision vernier scale with 0.2g minimum division and total 5g measuring range, for refined practice of vernier reading and slider adjustment. When weights cannot fully balance the scale, move the slider for fine tuning and understand the complete weighing concept: "weights for coarse adjustment, vernier slider for fine adjustment".
Built-in standardized experiment sheet containing complete fields: experimenter, experiment time, experiment topic, experiment principle, experimental data and summary. Standardized entry fosters rigorous scientific recording habits, seamlessly compatible with real lab reports.
The system automatically saves all experiment records. You can view historical data anytime, review your full learning journey, compare operations and results of multiple experiments, spot and correct reading and operation deviations.
Supports file export, email sending, social platform sharing and more. Convenient for students to submit homework, hold class and group discussions; convenient for teachers to collect and grade experiment records.
