The dictionary definition of Resistance is: Any force that slows down or prevents motion.
Resistance is a scientific term that stems from Newton’s laws of motion. An object in motion stays in motion until subjected to an outside force. For every action, there is an equal and opposite reaction. Resistance plays a crucial part in how the universe works.
Without mechanical resistance, your car wouldn’t stop (or start, for that matter). Without electrical resistance, lightbulbs wouldn’t glow. And without change resistance, organizations wouldn’t work.
