forces acting on a hockey puck

When the air around the puck becomes turbulent, it creates a swirling motion that creates additional drag. However, the effect of magnetic fields on a hockey puck is generally considered to be negligible compared to other forces like friction and impact forces. Figure 9 shows an example of the motion of the centre of mass, with constant angular momentum but shrinking radius. This paper investigates an alternative stride, with a longer gliding phase in a circular arc, where the centripetal force provided by the ice acting on the skates changes the direction of motion, without the need for additional energy. However, launching the puck too high may result in a slow descent, giving the opposing team time to intercept the puck. If its velocity relative to a given frame is constant, then that frame is said to be inertial. Science. Even if the puck is on ice, I wouldnt automatically assume no friction. (e) Skate S2 pushes the body towards the centre of the circular arc. Friction is an external force that causes an object to slow down. How the Magnetic Properties of the Puck Affect the Game of Hockey. Ice hockey skating is characterized by rapid starts, runs, stops and turns. While sliding a couch across a floor, Andrea and Jennifer exert forces [latex] {\overset{\to }{F}}_{\text{A}} [/latex] and [latex] {\overset{\to }{F}}_{\text{J}} [/latex] on the couch.

This paper considers how the fundamental physical concepts of classical mechanics can be applied to an understanding of fast forward skating and a comparison between traditional hockey skating to an unconventional technique based on conservation of angular momentum. Example 10.4: For each of the following situations, list the forces acting on each object, name the object exerting the force, describe the reaction force and name the object that feels the reaction force . However, from the system of the skater, moving along the track to the right, we could consider work done by the extending right leg to achieve the new velocity. According to Newtons first law, there must be a cause for any change in velocity (a change in either magnitude or direction) to occur. Although ice is very slippery, there will be a frictional force between it and the puck, which acts against the forward motion meaning you must account for it. The third row in figure 1 shows the right skate making contact with the ice, and the left skate pushing it closer to the centre of the arc. The authors would like to thank professor Cecilia Jarlskog for bringing us together. This means that in essence, every object is a point a thing with no dimensions whatsoever. At higher altitudes, there is less air resistance due to the lower air density, while colder temperatures can make the air denser and increase air resistance. The diagram with both arrows pointing in the same direction. One way to reduce friction is by regularly cleaning the ice with a zamboni machine to ensure a smooth playing surface. So what about hitting the puck around an entire hockey rink (about 180 m, in the shape of a rounded rectangle) with one shot? When the air is off, friction quickly slows the puck; but when the air is on, it minimizes contact between the puck and the hockey table, and the puck glides far down the table.
