Types of forces in physics with examples and their interactions form the foundation of understanding motion and physical interactions.
• Forces are pushes or pulls that can change an object's speed, shape, or direction, always acting in pairs.
• Contact forces require physical touch between objects, including friction, tension, and normal reaction force.
• Non-contact forces work at a distance, such as gravity, magnetic, and electrostatic forces.
• Understanding balanced and unbalanced forces is crucial for predicting object motion.
• How friction affects motion in physics is demonstrated through its role as a resistive force between surfaces.
