Pendulums
Practice
practice problem 1
A "seconds pendulum" has a half period of one second. It takes one second for it to go out (tick) and another second for it to come back (tock).
- What is the length of a seconds pendulum at a place where gravity equals the global average value of 9.81 m/s2?
- What is the period of this same pendulum if it is moved to a location near the equator where gravity equals 9.78 m/s2? How much time does the pendulum lose or gain every 30 days?
- What is the period of this same pendulum if it is moved to a location near the north pole where gravity equals 9.83 m/s2? How much time does the pendulum lose or gain every 30 days?
