Simple Harmonic Motion

Question 1

Defining equation of SHM?

Answer 1

a = -ω^2x

Simple harmonic motion is an oscillation in which the acceleration of an object is directly proportional to its displacement from the midpoint, and is directed towards the midpoint.

Question 2

Why is a ball bouncing off the ground not considered SHM?

Answer 2

The ball slows down and therefore the acceleration is not directly proportional to its displacement from the midpoint.

Question 3

What is the condition for SHM?

Answer 3

An oscillation in which the acceleration of an object is directly proportional to its displacement from the midpoint, and is directed towards the midpoint.

Question 4

Where is the Kinetic energy at its maximum?

Answer 4

The midpoint

Question 5

When is the potential energy at a maximum?

Answer 5

When the object is furthest from the midpoint.

Question 6

In SHM the frequency and period are independent of amplitude. True or False?

Answer 6

True

A pendulum clock will keep ticking in regular time intervals even if its swing becomes very small.
