Tape experiment how to pull at constant speed?

Click For Summary
SUMMARY

The discussion focuses on conducting a physics experiment to measure the relationship between peeling force and peeling velocity of tape. A high school student seeks a method to pull tape at a constant speed, initially attempting to use a motor connected to a spring, which proved ineffective due to insufficient motor strength. A recommended solution involves using a weight falling vertically attached to a string, which can maintain a constant force throughout the experiment, ensuring consistent velocity and accurate measurements.

PREREQUISITES
  • Understanding of basic physics concepts, particularly force and velocity.
  • Familiarity with experimental design and measurement techniques.
  • Knowledge of the mechanics of pulleys and weights.
  • Experience with using springs and their limitations in force applications.
NEXT STEPS
  • Research methods for maintaining constant velocity in physics experiments.
  • Learn about the mechanics of using weights and pulleys in experiments.
  • Explore the principles of force measurement in adhesive materials.
  • Investigate alternative methods for applying constant force in experiments.
USEFUL FOR

This discussion is beneficial for high school physics students, educators conducting experiments on adhesive properties, and anyone interested in the mechanics of force and motion in experimental setups.

hi all
i'm a high school student doing a physics experiment about the peeling force of a tape.
I want to see the realtionship between the peeling force and the peeling velocity but I cannot think of a good way to pull at constant speed.
I tried to connect the spring to a motor so that the motor would pull the spring at a constant speed but the motor is not strong enough.

how can I pull at a constant velocity and measure the force with the peeling angle and all other things kept constant?

please help me! :D

Probably, you will get a constant velocity if you pull with a constant force.

One way to do that is have a weight falling vertically, attached to a string that applies the force to the rest of the experiment.

Using a spring is a bad idea, because the force will change depending on how much the spring is stretched.
