Question
An object is released from rest. The time it takes to fall through a distance h and the speed of the object as it falls through this distance are measured with a pendulum clock. The entire apparatus is taken on the moon and the experiment is repeated:
  1. The measured times are same.
  2. The measured speeds are same.
  3. The actual times in the fall are equal.
  4. The actual speeds are equal.
✓

Answer

  1. The measured times are same.
  2. The measured speeds are same.
Explanation:
The effect of gravity on the object as well as on the pendulum clock is same in both cases the time measured is also same. As the time measured is same, the speeds are same.
