IB Physics SL C 4 5 Damping and Resonance Questions question 1
This question is in two parts. Part 1 is about solar radiation and the greenhouse effect. Part 2 is about a mass on a spring.
Part 1 Solar radiation and the greenhouse effect
The following data are available.
Question (a)
(a)
Outline the conditions necessary for the object to execute simple harmonic motion.
[ 2 ]
Question (i)
(i)
Sketch on the same axes a graph of how the displacement varies with time if a small frictional force acts on the object.
[ 2 ]
Question (b)
(b)
Point P now begins to move from side to side with a small amplitude and at a variable driving frequency f. The frictional force is still small.
At each value of f, the object eventually reaches a constant amplitude A.
The graph shows the variation with f of A.

Question (i)
(i)
On the same axes, draw a graph to show the variation with f of A when the frictional force acting on the object is increased.
