Simple harmonic motion CGP pg 100 to 101 Flashcards
Simple harmonic motion is defined in terms of… And…
Acceleration
Displacement
How does An object moving with simple harmonic motion oscillate
The distance of the object from the midpoint is called the
It oscillates To and fro either side of a Midpoint
Displacement
There’s always a restoring force pulling or pushing the object ..
Back towards the midpoint
The size of the restoring force is
Directly proportional to the displacement
I.e if the displacement doubles the restoring force doubles too
As the restoring force causes acceleration towards the midpoint we can also say
The acceleration is directly proportional to displacement
Condition for simple harmonic motion
A is directly proportional to -displacement
There’s a negative sign because
An oscillation in which the acceleration of an object is directly proportional to its displacement from the midpoint and is directed towards the midpoint
The acceleration is opposing the displacement
The Restoring force makes the object
Exchange potential energy and gravitational energy
