Also what is its's equation The rate of change of angle. ω=θ/t (this t is for time) 1 of 27 State the equation of ω when time is equal to one period ω=2π/T 2 of 27 State the relationship between linear velocity and angular velocity V=rω 3 of 27 What is centipetral acceleration The acceleration of any object travelling In a circular path at constant speed 4 of 27 State the equation of acceleration in simple harmonic motion a=-ω squared multiplied by x (the distance) 5 of 27 In simple harmonic motion is the period of the swing independent to the amplitude Yes 6 of 27 What is free oscillations in simple harmonic motion When there's no driving mechanism and the object continues to move after it has been set to oscillate 7 of 27 What is forced oscillations in simple harmonic motion When the object is cause to vibrate by a periodic driving force 8 of 27 What is simple harmonic motion Motion where an object has an acceleration that's directly proportional and in the opposite direction to displacement 9 of 27 Equation for period when experimenting simple harmonic motion of a pendulum T= 2π multiplied by square root of L/g 10 of 27 Equation for period when experimenting simple harmonic motion of a spring system T=2π multiplied by square root of mass/ spring constant 11 of 27 Does the mass of the bob affect time period No 12 of 27 Does length of the string affect time period Yes 13 of 27 The two Equations for displacement x=Acosωt (t for time ) x=Asinωt 14 of 27 When do you use the equation x=Acosωt When th oscillation begins from amplitude 15 of 27 On a spring mass system what potential energies act Gravitational potential and elastic potential 16 of 27 What is damping When an external force that acts on the oscillator has the effect of reducing the amplitude of the oscillations 17 of 27 Name the three types of damping Light damping , heavy damping , critical damping(very heavy damping) 18 of 27 What is light damping When small damping forces are applied and the amplitude of the oscillator gradually decreases with time without affecting the period 19 of 27 What is heavy damping When larger damping forces causes the amplitude to decrease significantly and the period of oscillations also increases slightly 20 of 27 Give an example of light damping Pendulum oscillating in air 21 of 27 Give an example of heavy damping Pendulum oscillating in water 22 of 27 Give an example of critical damping(very heavy damping) Pendulum moving through oil 23 of 27 What is the frequency of a free oscillation called Natural frequency 24 of 27 What is the frequency of a forced oscillation called Driving frequency 25 of 27 What happens if the driving frequency and the natural frequency of an oscillating object is equal It will resonate 26 of 27 What happens if you don't damp a system that's resonating The amplitude will increase causing the system to break 27 of 27
