Fundamental Forces in Nature: Fundamental Forces in Nature

This lesson covers three types of universal forces: Earth's gravity, electromagnetic forces, and nuclear forces. Earth's gravity is an attraction force based on mass. Electromagnetic forces involve electricity and magnetism, crucial for devices like generators and motors. Nuclear forces are divided into weak and strong types, with applications in medicine, research, energy production, and military uses.
