Dynamics: What are Forces?

The video tutorial introduces key physics terms like work, energy, and force, emphasizing their specific definitions in physics. It transitions from kinematics to dynamics, focusing on the study of forces and their effects on motion. The tutorial explains forces, vectors, and freebody diagrams, and distinguishes between contact and non-contact forces, including examples. It introduces the four fundamental forces and the unit of force, Newton, named after Sir Isaac Newton, who formulated the laws of motion.

Describe the difference between contact forces and non-contact forces.
