Answer:
Force
Explanation:
Force is a pull or push that causes An objects motion to change . When force is applied to an object , it either pushes the object to or pulls it from something thereby changing the motion of the object. A good example is the earth’s gravitational force. This force pulls or attracts a body to the center of the earth . Another example Is experienced when kicking a football from one part of a football field to another. The ball is kicked with force and this causes it to move from one place another .
Its acceleration will change
The word to fill in the blank is "equal". Because the time taken to rotate (spin on its axis) is equal to the time of revolution (going around the earth), this means that both have the same rate of angular rotation. So for every bit that the moon goes around its orbit around earth, the moon itself rotates accordingly to present the exact same side to earth.
