Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Earth’s moon stays in orbit around Earth due to ____
A
speed
B
mass
C
energy
D
gravity
Explanation: 

Detailed explanation-1: -The reason is that the Moon is never still. It constantly moves around us. Without the force of gravity from the Earth, it would just float away into space. This mix of velocity and distance from the Earth allows the Moon to always be in balance between fall and escape.

Detailed explanation-2: -Newton concluded that the orbit of the Moon was of exactly the same nature: the Moon continuously “fell” in its path around the Earth because of the acceleration due to gravity, thus producing its orbit.

Detailed explanation-3: -The moon revolves around the earth in a similar way but due to the velocity with which the moon got hooked onto the earth’s gravity keeps it from falling onto the earth. This keeps the moon in a pretentious orbit around the earth even though it is moving further away from our planet by an ever so little margin.
