A free-body diagram is a visual representation that shows all the forces acting on an object. It helps analyze and understand how different forces affect the motion of an object.
Force is any push or pull that can cause an object to accelerate, decelerate, or change shape.
Net force is the vector sum of all individual forces acting on an object. It determines whether there will be any change in motion.
Equilibrium occurs when there is no net force acting on an object, resulting in balanced forces and no change in motion.
