Forces on pendulum Physics Dynamics
Pendulum.JPG

Overview:

The animation shows the weight, the force due to tension and the total force exerted on the bob of a pendulum.

You may:

  • Pause the simulation
  • Follow the oscillation step by step, in both back and forth motion


Suggestions:

Analyse the process for each of the three intervening forces.

Pay special attention to the extrema and to the mid point of the oscillation.

Explain the directions of the forces in those points in a general position.

Relate qualitatively the total force to the normal and tangential values of the acceleration.

Terms you need to know:

Tarzan, represented by a blue ball, is swinging from a 55 meter massless vine. Air resistance is negligible
We also show Tarzan's weight, the force exerted on him by the tension of the vine, and the sum of these two forces
Click to pause
Tension (in units of Tarzan's weight)
Click to resume
Or click these to single step
