What is simple harmonic motion (SHM)?
Simple harmonic motion is a type of oscillatory motion where the acceleration of a system is directly proportional to its displacement from the mean position.
What is Hooke's law?
Hooke's law states that the force exerted by a spring is directly proportional to the change in length of the spring, which is the displacement of the mass from its mean position.
What does the spring constant (k) measure?
The spring constant (k) measures the stiffness of the spring.
What type of energy does a mass-spring system have at the maximum displacement (x = ±A)?
At the maximum displacement (x = ±A), the mass-spring system has maximum potential energy (P.E) and zero kinetic energy (K.E).
What does the negative sign in the equation for potential energy indicate?
The negative sign in the equation for potential energy indicates that the potential energy is at its maximum when the displacement is zero.
Give an example of a system that exhibits simple harmonic motion (SHM).
A mass attached to a spring on a horizontal frictionless surface, a ball placed in a bowl, or a bob attached to a string are examples of systems that exhibit simple harmonic motion.
What is the force exerted by the spring always directed towards?
The mean position
What is the restoring force's effect on an object performing oscillatory motion?
It always pushes or pulls the object towards the mean position
What is the magnitude of the restoring force at the mean position?
Zero
What is the resultant force on the mass when it is initially at rest in position O?
Zero
What happens to the speed of the mass as it moves towards the mean position?
It becomes maximum
What is the motion of a mass attached to a spring on a horizontal frictionless surface known as?
Simple Harmonic Motion (SHM)
At which position does the mass briefly come to rest during the oscillatory motion?
At the extreme position B
What is the equation for the time period T of simple harmonic motion?
T = 2π√(m/k)
What happens to the restoring force as the mass moves from the mean position to the extreme position B?
It steadily increases in strength
What happens to the speed of the mass as it moves towards the extreme position B?
It decreases
