Spark Timer Kit for Physics Experiments

The Spark Timer Kit is designed to measure the speed of a moving cart, investigate friction forces in dynamics, and determine the rate of acceleration in a falling body in a vertical position. It features a spark generator that creates sparks at precise intervals, burning tiny dots into the paper tape as it is pulled through the timer. The faster the tape moves, the larger the distance between the dots, allowing students to calculate the speed and acceleration of the object. For convenience, the recording needle is raised when the timer is turned off, making it easy to insert or remove the tape.

Key Features:

Accurate Time Measurement: The spark generator creates sparks at precise intervals, burning dots into the paper tape. This allows for accurate calculations of speed and acceleration.
Three-Stage Frequency Settings: Equipped with 20Hz, 50（60Hz）, and 100Hz settings, it provides clear prints even for slow-moving dynamic carts.
Easy Tape Insertion/Removal: The recording needle is automatically raised when the timer is turned off, making tape changes quick and easy.

Merit

Precision and Accuracy: Provides exact time intervals for detailed analysis of motion and forces.
Educational Value: Enhances understanding of fundamental physics concepts through hands-on experimentation.
Easy to Use: Simple setup and operation make it accessible for students and educators.

Tips:

Setup: Attach the spark timer kit securely to a table using the provided clamp.
Load the Tape: Thread the recording tape through the spark timer, ensuring it is taut and aligned.
Select Frequency: Choose the appropriate frequency setting (20Hz, 60Hz, or 100Hz) based on the speed of the object being studied.
Conduct Experiments: Run your experiments, whether measuring speed, investigating friction, or determining acceleration, and observe the dot patterns on the tape.
Analyze Results: Measure the distance between dots to calculate time intervals, speed, and acceleration. For more precise measurements, use a 10-tick interval and divide the distance by the time for the 10-tick interval.
