* Direct Observation: We can directly observe and measure the mass of an object through its weight or inertia (resistance to change in motion). We can see how much space an object takes up (volume) and feel its heaviness.

* Everyday Experience: We encounter mass constantly in our daily lives. We lift objects, push things, and see things fall due to gravity, all of which are related to mass.

* Charge is Hidden: Electric charge is less obvious. While we experience the effects of charge (like static electricity or a shock), we don't directly see or feel the charge itself.

* Neutral Objects: Most objects around us are electrically neutral, meaning they have equal amounts of positive and negative charges, canceling each other out. This makes charge less apparent.

In summary: Mass is a fundamental property that we experience directly through our senses and observations, while charge is a more subtle property that is often hidden or masked by neutrality.
