# How does a hockey puck slide?

Contents

Friction – Friction is the force that takes place when one object slides against another. As one thing slides more quickly along the surface, heat is created. So, as hockey players push the puck along, friction causes the slightest warmth, melting the ice the tiniest bit and making it easier for the puck to slide.

## Does a puck have friction?

You start with the ice, which is a very slippery surface – so it’s safe to assume that the friction between the puck and the ice is negligible. … 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.

## What forces act on a hockey puck sliding on the ice rink?

For example, if I take a slap shot on a hockey puck, from what I understand, the forces acting on the puck are friction, the normal force, and the puck’s weight.

## What type of friction is in hockey?

In ice hockey, and in skating in general, the speed of movement is limited by two main resistances: the aerodynamic drag resistance (RA, in N) and friction resistance (RF, in N) between the ice and the skate blade (Fig. 1).

## Why might a hockey puck slow down as it slides along the ice?

A hockey puck slides along the ice. There is a frictional force between the ice and puck, and this is the only horizontal force on the puck. … The puck will slow down and eventually come to rest.

## Why do things slide on ice?

Because ice is less dense than liquid water, its melting point is lowered under high pressures. A long-standing theory says that this is what causes ice to be slippery: As you step on it, the pressure of your weight causes the top layer to melt into water.

## How far does the puck slide before coming to rest?

The puck remains on the ice and slides 120m before coming to rest. How can the coefficient of friction between the puck and the ice be determined? Use the kinematic formula, along with the knowledge that the puck’s acceleration is kg, where k is the coefficient of kinetic friction, and g is the acceleration of gravity.

## Is hockey sliding friction?

Friction – Friction is the force that takes place when one object slides against another. … So, as hockey players push the puck along, friction causes the slightest warmth, melting the ice the tiniest bit and making it easier for the puck to slide.

## Why does a hockey puck moving across smooth ice move at a constant velocity?

These two forces cancel to give a net force of zero in the vertical direction. Since no external force acts in the horizontal direction, according to Newton’s first law, the hockey puck will continue to move at a constant velocity.

## How hard do hockey players hit the puck?

An ice hockey player can strike a puck at speeds up to about 45 m/s (100 mph) using a technique known as the slap shot.

## How does a hockey puck slow down?

Friction is the loss of kinetic energy into thermal energy, which is why the block slows down. So let’s think about this—can you relate this to hockey? The players each have a hockey stick and they want to hit the puck into the goal.

## How is physics involved in hockey?

Hockey tricks rely on physics

The player turns sideways to the goal, winds up with the stick behind him, and then swings through the puck. The power for the shot comes from the player transferring his weight from the back legs through the body, down the arms and right through to the stick.

## How fast does a hockey puck go?

Does the temperature of a hockey puck affect how far it will travel? Both pucks will travel the same distance across the ice, but the warmer puck will bounce further and can therefore cover more of the ice with the same force.

## What is the average acceleration of the puck as it slides across the ice?

The puck’s acceleration is –4.6 m/s2 [fwd].
