The greater the mass of the body, the greater
the answer: inertia
According to Newton's law of motion, the greater the mass of an object, the greater its inertia.
In other words, the larger the object's size, the greater its resistance to changes in its motion.
This is why moving a heavier object requires more force than moving a lighter object.
This also explains why heavier objects need more energy to accelerate them to a certain speed.
Moreover, the greater the mass of an object, the stronger its gravitational pull, which means it will have a stronger pull on other objects next to it.
This can be seen in everyday life, from the ability of large planets to attract and hold their moons to the fact that apples fall from trees due to Earth's gravity.
