SIMPLE HARMONIC MOTION | Part 2

STATEMENT-1 : An oscillatory motion is always simple harmonic motion. STATEMENT-2 : A simple harmonic motion is always oscillatory motion.

STATEMENT-1 : In simple harmonic motion, at extreme position the velocity and acceleration of object is zero. STATEMENT-2 : In simple harmonic motion at mean position?

Statement-I : In simple harmonic motion, the graph between velocity and the displacement is an ellipse. Statement-II : In simple harmonic motion the phase difference between velocity and displacement is pi//2 .

Assertion: The simple harmonic motion is to and the fro and periodic Reason : The motion of the earth is periodic

Assertion : Acceleration is proportional to the displacement. This condition is not sufficient for motion in simple harmonic. Reason : In simple harmonic motion direction of displacement is also considered.

STATEMENT-1 : The phase difference between acceleration and velocity in simple harmonic motion is 90^(@) . STATEMENT-2 : The tim e period in case of simple harmonic motion is independent of amplitude of vibration.

The equation of motion of a simple harmonic motion is

A particle executes simple harmonic motion under the restoring force provided by a spring. The time period is T. If the spring is divided in two equal parts and one part isused to continue the simple harmonic motion, the time period will
