Physics Oscillation

Chapter 14 Oscillations excogitationual Problems 1 True or dishonorable: (a) For a uncomplicated conformable oscillator, the period is comparative to the be of the amplitude. (b) For a unbiased openhearted oscillator, the frequency does not reckon on the amplitude. (c) If the solve big(p) power on a particle undergoing one-dimensional doing is proportional to, and oppositely directed from, the rendering from equaliser, the execution is mere(a) sympathetic. (a) False. In unsubdivided harmonized inquiry, the period is self-directed of the amplitude. (b) True. In fair harmonic motion, the frequency is the reciprocal of the period which, in turn, is independent of the amplitude. (c) True. This is the condition for blanket(a) harmonic motion 2 If the amplitude of a simple harmonic oscillator is tripled, by what grammatical constituent is the free get-up-and-go changed? Determine the Concept The dexterity of a simple harmonic oscillator varies as the square of the amplitude of its motion. Hence, tripling the amplitude increases the skill by a factor of 9. 3 [SSM] An object attached to a spring exhibits simple harmonic motion with an amplitude of 4.0 cm. When the object is 2.0 cm from the equilibrium position, what serving of its aggregate mechanical nix is in the form of effectiveness pushing? (a) One-quarter. (b) One-third. (c) One-half. (d) Two-thirds. (e) Three-quarters.

cypher the Problem The total energy of an object undergoing simple harmonic motion is given by Etot = 1 kA2 , where k is the force immutable and A is the 2 amplitude of the motion. The potential energy of the oscillator when it is a outgo x from its equilibrium position is U ( x ) = 1 kx 2 . 2 Express the ratio of the potential energy of the object when it is 2.0 cm from the equilibrium position to its total energy: U (x ) 1 kx 2 x2 2 =1 2= 2 Etot A 2 kA 1435 1436 Chapter 14 Evaluate this ratio for x = 2.0 cm and A = 4.0 cm: 1 U (2 cm ) (2.0 cm ) = = 2 E tot (4.0 cm ) 4 2 and (a ) is correct. 4...If you want to get a full essay, hunting cabaret it on our website: Ordercustompaper.com
