* No Friction: Since the surface is frictionless, there's no force opposing the puck's motion. This is the key difference from a puck on a regular surface.
* No Air Resistance: We're assuming an idealized scenario where air resistance is negligible.
* Gravity: The puck experiences the force of gravity pulling it downwards. However, since it's moving horizontally, this force is balanced by the table's normal force.
* Normal Force: The table exerts an upward force on the puck, equal in magnitude and opposite in direction to gravity, keeping the puck from falling through the table.
Therefore, the net force acting on the puck is zero. This is consistent with Newton's First Law of Motion, which states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Key takeaway: Since there's no net force, the puck continues to move at a constant speed in a straight line.
