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. Mathematically, this is represented as F = ma, where:

* F is the net force

* m is the mass of the object

* a is the acceleration

* Small Force, Small Acceleration: If the force is small, the resulting acceleration will also be small, assuming the mass of the human-sized object remains constant.

Examples:

* A gentle push: A gentle push on a person might cause them to move slowly. The force is small, and the resulting acceleration is also small.

* A feather landing on your hand: A feather landing on your hand exerts a very small force. You don't even notice it accelerating your hand.

Important Note:

Even a small force can have a significant effect over time. Think about a slowly dripping faucet. Over time, the force of the water can erode a hole in the sink.
