Physics "Magic Trick" on an Incline

The video tutorial demonstrates a physics-based magic trick involving a block on an incline. The instructor calculates the incline angle using trigonometry and identifies the forces acting on the block. By applying Newton's second law, the magnitudes of these forces are determined. The magic trick is explained by replacing the board's forces with tension forces in strings, allowing the block to 'float' when the board is removed. The lesson concludes with a demonstration of the floating block, emphasizing the equilibrium of forces.
