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.
* Formula: This can be expressed as: a = F/m
* a = acceleration
* F = force
* m = mass
In simpler terms:
* More force, more acceleration: If you push harder on an object (increase the force), it will accelerate faster.
* More mass, less acceleration: If you make the object heavier (increase the mass), it will accelerate slower with the same amount of force.
Example: Imagine pushing a small toy car and then a large truck with the same force. The toy car will accelerate much faster than the truck because it has less mass.
