Question

When a mass hanging from a spring is pulled down and then released, the motion is called __________ . if there is no frictional force to retard the motion, and the motion is called ______ if there is friction.

Short answer

When a mass hanging from a spring is pulled down and then released, the motion is called Simple harmonic if there is no frictional force to retard the motion, and the motion is called Damped if there is friction.

Step-by-step solution

Given information

When a mass hanging from a spring is pulled down and then released, the motion is called _____ if there is no frictional force to retard the motion, and the motion is called ______ if there is friction.

Explanation

The type of motion created when pulling down an object suspended on a spring and there is no friction to retard the motion is simple harmonic

Also a similar type of motion but one where friction is present is called damped motion

Conclusion

When a mass hanging from a spring is pulled down and then released, the motion is called Simple Harmonic if there is no frictional force to retard the motion, and the motion is called Damped if there is friction.
