Why is the moon's gravitational attraction different than the gravitational attraction on earth

The circumference of the Moon is smaller than Earth, therefore it has less gravity. The lack of air pressure on the Moon weakens the gravitational force of the Moon. The mass of the Moon is less than that of Earth, therefore it has a weaker gravitational force.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
