Question

When we model a pendulum, we only include the force of gravity and the force of tension on the idealized string (or other contact force which serves to change the direction of motion of the pendulum). This idealized pendulum will swing forever. show answer No Attempt In real life, pendulums eventually stop moving. Why is this

Answer 1

Step-by-step explanation:

If we consider the ideal conditions, the force acting on the bob of the pendulum is only the gravitational force and the tension force in the string, s the pendulum keeps oscillating.

But in general practice, the pendulum stops after some time, it is due to the force of friction due to air and some dissipative forces due to the thread, etc. These force tries to stop the motion of bob and then eventually it stops.
