11- Modelling oscillations

Question 1

Equation for SHM if oscillator starts at max displacement?

Answer 1

x=Acoswt

Question 2

Equation for shm?

Answer 2

a =-w^2x

Question 3

What is free oscillation?

Answer 3

An oscillation due to the action of a restoring force, without any damping or driving force.

Question 4

What is natural frequency?

Answer 4

The frequency of a free oscillator.

Question 5

What is forced oscillation?

Answer 5

An oscillation driven by the action of a periodic driving force.

Question 6

Define resonance.

Answer 6

The effect produced when a driving frequency, matches the natural frequency of a system, resulting in large amplitude oscillations.

Question 7

Define damping.

Answer 7

The action of forces such as friction or air resistance to reduce the amplitude of an oscillator.
