The four key contact forces that you will read in Class 11 Physics are normal force, friction, tension, and spring force. Each of these forces needs physical contact and follows Newton's Third Law. They come into play during motion, compression, stretching, or when objects rest on surfaces. These contact forces help in drawing the free-body diagrams (FBDs) and solving problems related to the laws of motion.
