Here's why:
* Newton's Second Law of Motion: This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
* Inertia: Mass is a measure of an object's inertia, which is its resistance to changes in motion. The more massive an object is, the harder it is to get it moving or to stop it once it's in motion.
In simpler terms:
Imagine pushing a small toy car and a large truck. You'll need much more force to get the truck moving (or to stop it) because it has more mass and therefore more inertia.
