The answer is C) The greater force and we will just ignore answer D because maybe the object is not even on the Earth. It could be floating in space.
Explanation:
It seems logical but let´s try to picture it to understand it better. Imagine a block sitting on the floor here on Earth. You are 10 years old and will compete against your 20 year old brother to see who can push harder and move the block in the direction of the other.
You are pushing as hard as you can and the block is not moving, Why? Because the net forces are equal. You have the floor pushing on the object as hard as the object is pushing on the floor due to the Earth´s gravity. Then you are pushing as hard as you can and your brother is pushing as hard as you, thus the block does not move. Next thing, your brother says he´s now going to push for real and you start moving backwards along with the block, Why? Because your 20 yo brother is now unbalancing the net forces on the block and accelerates the block in the direction of the greater force he is applying and the block will not stop moving until it finds enough resistance to do so.
Flexibility is the ability of a joint or series of joints to move through an unrestricted, pain free range of motion. ... These soft tissues include: muscles, ligaments, tendons, joint capsules, and skin.
