Cards in this deck (14)
- 1Where is the displacement in SHM measured from?The equilibrium posistion
- 2What kind of graph does a time displacement graph give for SHM?A sine wave.
- 3What is the amplitude in SHM?The maximum displacement of an object from equilibrium
- 4What is phase difference in radians?2π∆t
-------------
T - 5Draw a displacement, velocity and acceleration time graph for SHM
- 6Where is the magnitude for velocity the greatest?When the gradient of displacement time graph is greatest, hence when the object is at equilibrium position after being released from max amplitude
- 7How does acceleration vary with time.Greatest when v-t gradient greatest. When velocity is at zero. Acceleration is zero when v-t m is zero. So at maximum displacement
- 8What is the acceleration always opposite to?The displacement.
- 9Define Simple harmonic motionOscillating motion in which acceleration is:
Proportional to the displacement
Always opposite to the displacement
a ∝ -x - 10What does a shorter time period mean for oscillations?The faster the oscillation and larger accelerations at any given displacement.
- 11What is the proportionality constant in a ∝ -xω^2
- 12Describe the energy change in one oscillation of a vertical spring starting at maximum compression.Gravitational Potential energy -> Kinetic energy -> Elastic potential energy -> Kinetic energy -> Gravitational Potential Energy
- 13Describe how the total potential energy of a vertical spring oscillation changes through one period.The total potential energy reaches two maximums, It has a maximum at beginning of oscillation as GPE and one at the bottom as Elastic p.e
