What characterizes the restoring force in Simple Harmonic Motion (SHM)?
What characterizes the restoring force in Simple Harmonic Motion (SHM)?
The restoring force in SHM is always directed towards the equilibrium position and is directly proportional to the displacement from that position.
How can the SHM of a simple pendulum be mathematically represented?
How can the SHM of a simple pendulum be mathematically represented?
The SHM of a simple pendulum can be represented by the equation $ma = -kx$, where $a$ is acceleration and $x$ is displacement.
What role does the spring constant play in the behavior of a spring system undergoing SHM?
What role does the spring constant play in the behavior of a spring system undergoing SHM?
The spring constant ($k$) determines the strength of the restoring force; a larger $k$ results in a greater restoring force for the same displacement.

Study Notes
Simple Harmonic Motion Overview
- Simple Harmonic Motion (SHM) is a periodic motion characterized by a restoring force that is proportional to displacement and acts towards equilibrium.
Conditions of SHM
- The restoring force must always act towards the equilibrium position.
- The magnitude of the restoring force is directly proportional to the displacement from equilibrium.
Mathematical Representation
- The equation representing SHM is:
- ma = -kx
- m: mass of the object
- a: acceleration
- k: spring constant
- x: displacement from equilibrium
- ma = -kx
Examples of SHM
-
Simple Pendulum:
- Composed of a small bob attached to a string of length L.
- When displaced and released, it exhibits SHM due to the gravitational restoring force that acts towards the equilibrium position.
-
Spring System:
- Consists of a mass connected to a spring.
- When the mass is displaced and released, it undergoes SHM as the spring exerts a restoring force defined by the equation:
- F = -k*x
- k: spring constant
- x: displacement from the equilibrium position
- F = -k*x
