- 1When doing a pendulum practical, what is 1 time period?If released from a point, its the time taken for it to come back to that point after it's released
- 2How could we make it easier to get a more accurate time period value?Time 10 time periods, and divide by 10
- 3Relationship between time period and mass : (pendulum)
- 4Small angles are angles which are....< 10 degrees
- 5Relationship between time period and θ : (pendulum)
- 6Relationship between time period and amplitude : (pendulum)
- 7Relationship between time period and length : (pendulum)
- 8T^2 against l (and T against root(l))
- 9Therefore this tells us:T^2 ∝ l
(or T ∝ root(l)) - 10Relationship between time period and amplitude : (mass-spring)
- 11Relationship between time period and mass : (mass-spring)
- 12T^2 against m (and T against root(m))
- 13This tells us:T^2 ∝ m
(or T ∝ root(m)) - 14Relationship between time period and spring constant : (mass-spring)
- 15T against 1/root(k) :
- 16This tells us:T ∝ 1/root(k)
- 17What is the pendulum equation for time period?T = 2π(root(l/g))
Correct for small angles
(g= gravity) - 18What is the mass-spring equation for time period?T = 2π(root(m/k))
- 19Maybe learn derivation of the time period formula:https://www.youtube.com/watch?v=MmwH1KNHBJE
