Ticker Tape Timer Kit for Physics Experiments
The Ticker Tape Timer Kit is a versatile tool designed for physics experiments to measure the speed of a moving cart, investigate friction forces in dynamics, and determine the acceleration rate of a falling body in a vertical position. This kit is ideal for both classroom demonstrations and individual student experiments, providing precise measurements and valuable insights into motion and forces.
Key Features:
- Accurate Time Measurement: The kit operates at a frequency of 50 Hz (50 cycles per second), making dots on the paper tape at intervals of 0.02 seconds. This allows for precise time measurement between successive dots.
- Electromagnet with Spring-Loaded Armature: The vibrating arm, driven by the changing current in the mains supply, ensures consistent dot marking on the ticker tape.
- Support Table: The carbon disc support table provides a stable surface for accurate dot placement.
- 4 mm Sockets: Fitted with color-coded red and black sockets at 19 mm spacing for easy connection and setup.
Applications:
- Speed Measurement: Measure the speed of a moving cart by analyzing the distance between dots on the ticker tape.
- Friction Investigation: Study the forces of friction in dynamic systems by observing the changes in dot spacing when different surfaces or materials are used.
- Acceleration Determination: Calculate the rate of acceleration for a falling body by examining the intervals between dots on the ticker tape.
Demonstration
- Speed of a Moving Cart: Attach the ticker tape to a cart and release it down a track. Measure the distance between dots to determine the cart’s speed.
- Friction Forces: Compare the dot spacing on ticker tapes for carts moving on different surfaces (e.g., smooth vs. rough) to study frictional forces.
- Free-Fall Acceleration: Drop a weighted object with the ticker tape attached from a known height and analyze the dot pattern to calculate the acceleration due to gravity.
Tips:
- Setup: Connect the ticker tape timer kit to a stable power source using the provided 4 mm sockets.
- Load the Tape: Thread the ticker tape through the armature and support table, ensuring it is taut and aligned.
- Conduct Experiments: Run your experiments, whether measuring speed, investigating friction, or determining acceleration, and observe the dot patterns on the ticker tape.
- Analyze Results: Measure the distance between dots to calculate time intervals, speed, and acceleration.
