1. Overview of a Frictionless Horizontal Air Table Puck

A frictionless horizontal air table is a device used to study the motion of objects in the absence of friction. It consists of a smooth, level surface on which a puck can glide with minimal resistance. The puck is a small, flat object that is placed on the table and can be moved by applying a force.

The characteristics of a puck on a frictionless horizontal air table include:

• Negligible friction: The puck experiences almost no friction as it moves across the table, allowing it to travel long distances with minimal loss of energy.
• Uniform motion: Once set in motion, the puck will continue to move at a constant velocity unless acted upon by an external force.
• Predictable trajectory: The puck’s motion is governed by the laws of motion, making it possible to accurately predict its path and velocity.

The assumptions and limitations of this system include:

• Idealized conditions: The frictionless horizontal air table is an idealized system that does not exist in reality. In practice, there will always be some degree of friction, but it is minimized to a negligible level.
• Limited applicability: The results obtained from experiments using a frictionless horizontal air table may not be directly applicable to real-world situations where friction is a significant factor.

2. Motion of a Puck on a Frictionless Horizontal Air Table

The motion of a puck on a frictionless horizontal air table can be described by the laws of motion. These laws state that:

1. An object at rest will remain at rest unless acted upon by an external force.
2. An object in motion will continue to move at a constant velocity unless acted upon by an external force.
3. The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

These laws can be used to predict the puck’s velocity, acceleration, and displacement under various conditions.

For example, if a puck is given an initial velocity of 1 m/s, it will continue to move at 1 m/s in the same direction unless acted upon by an external force. If a force of 2 N is applied to the puck in the opposite direction of its motion, it will experience an acceleration of -2 m/s^2 and its velocity will decrease by 2 m/s every second.

3. Collisions on a Frictionless Horizontal Air Table: On A Frictionless Horizontal Air Table Puck A

Collisions between pucks on a frictionless horizontal air table can be either elastic or inelastic.

• In an elastic collision, the total kinetic energy of the system is conserved. This means that the total kinetic energy of the pucks before the collision is equal to the total kinetic energy of the pucks after the collision.

• In an inelastic collision, some of the kinetic energy of the system is lost. This can happen when the pucks stick together after the collision or when they deform upon impact.

The conservation laws that apply to collisions on a frictionless horizontal air table include:

• Conservation of momentum: The total momentum of the system is conserved. This means that the total momentum of the pucks before the collision is equal to the total momentum of the pucks after the collision.
• Conservation of energy (for elastic collisions only): The total kinetic energy of the system is conserved. This means that the total kinetic energy of the pucks before the collision is equal to the total kinetic energy of the pucks after the collision.
