A free-body diagram is a visual representation that shows all the forces acting on an object. It helps to analyze and understand the motion of the object by isolating individual forces.
Imagine you are playing a video game where you control a character. The free-body diagram is like the HUD (heads-up display) that shows all the power-ups, obstacles, and enemies affecting your character. It helps you strategize and make decisions based on the forces acting on your character.
Net Force: The net force is the vector sum of all the individual forces acting on an object.
Frictional Force: Frictional force is a resistive force that opposes motion between two surfaces in contact.
Tension Force: Tension force is a pulling force transmitted through a string, rope, or cable when it's pulled at both ends.
