Resistance means pushing back against something or refusing to accept it. When you encounter resistance, you're meeting a force that opposes or slows you down.

In science, resistance describes how materials oppose the flow of electricity or how objects push back against motion. A thick rubber band offers more resistance when you stretch it than a thin one does. Water creates resistance when you try to run through a swimming pool, which is why moving through water feels harder than moving through air.

People show resistance too. If your parents suggest cleaning your room and you resist, you're pushing back against their request. During World War II, resistance fighters in occupied countries secretly opposed enemy armies, risking their lives to fight back against invasion. The French Resistance, for example, sabotaged enemy operations and helped Allied forces.

Resistance can be physical, like a door that resists opening because the hinges are rusty. It can be emotional, like resisting the urge to eat a second cookie when you know you’ve had enough. Scientists and doctors study antibiotic resistance, which happens when bacteria evolve to resist medicines that used to stop them.

The word carries different feelings depending on context. Sometimes resistance means stubborn refusal to accept good advice. Other times it means brave opposition to something wrong or unjust. Understanding when resistance serves you well and when it holds you back is part of growing wiser.
