Oscillations become damped due to
Answers
Answer:
When the motion of an oscillator reduces due to an external force, the oscillator and its motion are damped. These periodic motions of gradually decreasing amplitude are damped simple harmonic motion.
Answer:
frictional force
Explanation:
frictional force
CONCEPT:
Damped oscillation: When there is a gradual decrease in the amplitude of oscillatory motion, it is said to be damped.
The decrease in the amplitude is due to an external force that tends to slow down the oscillations.
An example of a damped motion is that of a simple pendulum.
The energy of the oscillation is decreased gradually and continuously in this type of motion.
The forces which dissipate the energy are generally frictional force.
Friction acts as an external force that resists the motion.
This frictional force acting opposite to the motion does negative work on the system and leads to the dissipation of energy.
As a result, the amplitude of oscillations decreases and gets damped.
So, the oscillations are damped due to the presence of frictional force.
