In ordinary life, things 'at rest stay at rest' and things that are moving move in straight lines unless additional forces act on those things.
The hockey puck has kinetic energy as it slides across the ice. This energy is due to the puck's motion and is directly related to its mass and speed.
No, air hockey puck bouncing off the sides of the table is not an example of projectile motion. Projectile motion involves an object being launched into the air and following a curved path due to gravity, while the puck in air hockey is typically sliding along a flat surface.
The mass of the puck does not affect its rotational motion in a circular path, only the force required to keep it in that path. The mass of the puck is the same whether it is rotating or not. The force keeping the puck in a circular path is provided by the tension in the string, which is determined by the speed of rotation and the mass of the puck.
In air hockey, when the puck hits the side of the table at an angle, it undergoes projectile motion as it bounces off the surface. The puck's velocity and direction change when it hits the side due to the perpendicular force exerted and the angle of impact. The puck follows a curved path as it rebounds, demonstrating the principles of projectile motion.
The main force acting on a frictionless air puck moving in a straight line across a table is inertia, which keeps the puck in motion. Additionally, there may be forces like gravity and normal force acting on the puck, but these forces do not affect its horizontal motion since the table is assumed to be horizontal.
Once contact with the object that provided the force to initiate the motion, i.e. your hand or the hockey stick, there is no force tending to keep it in motion. The inertia of the puck in motion will resist any change in that motion, but inertia is a physical property not a force. From a free body diagram the only apparent force acting on the puck would be air resistance tending to slow it down.
this makes no sense!!!! If you mean when the puck is in motion on the ice, it called the " puck in play " .

A hockey stick is required either way, but the type will affect whether you use a ball on a field or a puck on some ice.

a puck
A hockey puck
THE PUCK, you play hockey to get the puck.

False
When a hockey puck is struck with a hockey stick, it experiences a force that propels it forward at high speed. The impact transfers kinetic energy from the stick to the puck, causing it to accelerate rapidly across the ice. The angle and speed of the strike determine the puck's trajectory and distance traveled. Factors such as friction with the ice and air resistance also influence its motion.
