Product overview Manual pointer type model for demonstrating uniform circular motion and verifying the centripetal force formula. Designed for straightforward classroom demonstrations and student experiments, the device emphasizes intuitive observation and handson learning. Key benefits Demonstrates fundamental physics clearly: Provides a direct, visual way to explore uniform circular motion and to verify the centripetal force relationship. Simple to use and teach: Manual pointer design and simple structure reduce set up time and make the experiment accessible for all skill levels. Improves learning outcomes: Encourages observation, questioning, and linking textbook theory to real situations, which helps students retain concepts. Supports inquiry and research: Supplied experimental ideas and illustrative images help teachers and students expand investigations, including hypotheses about charged particle motion. Obvious experimental effects: Motion and force relationships are easy to observe, making results clear during demonstrations. Functions and key attributes Primary functions: Model uniform circular motion and verify the centripetal force formula through direct, manual operation. Design type: Manual pointer type with a simple, easytooperate structure. Educational compatibility: Suitable for standard physics curricula, school laboratory setups, and classroom demonstrations. Usability: Low setup complexity and intuitive operation make it ideal for use in lectures, labs, and informal learning sessions. Instructional material: Includes simple experimental ideas and pictures to guide initial experiments and inspire further investigation into related phenomena such as charged particle motion. Practical performance Clear, observable motion that highlights the relationship between speed, radius, and centripetal force. Reliable for repeated classroom demonstrations and student practice because the manual design places control in the user hands. Promotes active learning through handson manipulation and visual verification. Suggested use scenarios 1. Classroom demonstration: Use the model at the front of the class to show how changing radius or rotational speed affects centripetal force, then derive the centripetal force formula together with students. 2. Student laboratory experiment: Small groups can perform guided measurements, record observations, and compare results with theoretical predictions to practice experimental method and data analysis. 3. Project and research exploration: Use the provided experimental ideas and images as a starting point to investigate related hypotheses, for example visual analogies to charged particle motion in uniform fields. What makes this product stand out Focused on clarity and intuition rather than complex electronics, making the physical relationships easy to perceive. Designed to link theory with practice, supporting both teaching and exploratory learning. Comes with ready prompts and visual guides to speed lesson preparation and encourage further inquiry. Who should consider this product Physics teachers and laboratory instructors who need a reliable, easytouse demonstration tool. Students learning mechanics who will benefit from handson verification of theoretical formulas.
