# Why does a hockey puck slide farther on ice than on concrete?

## 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.

## Which force keeps an ice hockey puck from sliding forever?

No net force means no movement, so you apply a pushing force, such as a hit from a hockey stick, which results in the puck travelling at a constant speed forever.

## What will happen to a hockey puck that is sliding along the ice if friction is acting?

If two systems are in contact and moving relative to one another, then the friction between them is called kinetic friction. For example, friction slows a hockey puck sliding on ice.

## Why can a hockey puck on ice move with constant velocity for a long time without anything pushing on it?

A hockey puck slides on ice at constant velocity. What is the net force acting on the puck? ZERO: The puck is moving at a constant velocity, and therefore it is not accelerating. Thus, there must be no net force acting on the puck.

## 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. … Just a layer of water will not do it.”

## What is the net force of a puck sliding across frictionless ice?

Since ice is frictionless, then frictional force is zero and there is no other external force is acting on the puck in the horizontal direction. Hence, the net force acting on the puck is zero and it glides with constant velocity.

## Is a hockey puck sliding at a constant speed a balanced force?

A hockey puck slides across the ice at a constant speed. … The puck can be considered neither at rest nor in equilibrium.

## Why does the puck slow down after being hit?

When a hockey stick collides with a puck, the puck squashes slightly and the stick bends due to the force on the stick. The force on the puck is equal to the force on the stick but acts in the opposite direction. As a result, the puck speeds up and the stick slows down.

## Is the hockey pucks motion at a constant speed?

A hockey puck slides across the ice at a constant speed. … Yes, because it reaches dynamic equilibrium when it moves in a straight line with unchanging speed.

## Does it take a force to keep a hockey puck moving on frictionless ice?

(d)A hockey puck sliding across frictionless ice. … (d)The hockey puck moves along at a constant velocity because no forces act on it. The point here is that objects can continue moving in a straight line with a constant speed even when no force acts on them.

## What kind of motion is the puck moving with?

The puck does not change direction, nor does it slow down or speed up but instead moves at a constant speed. Newton’s laws state that when the puck is at rest or coasts at a constant rate in a straight line, there is no net force acting on the puck.

## How does an air puck work?

The puck moves on a cushion of air. The tube that supplies the air also includes a fine chain that is connected to a high voltage source called a spark timer. The voltage source produces a spark between the centre of the puck and the carbon paper at precise intervals.

## What force is required to keep the puck moving?

No force is required to keep the puck moving. The puck has inertia and by Newton’s 1st Law, an object moving with constant velocity will continue to move with constant velocity unless acted on by an external force.

## When a constant net force acts on an object?

A constant net force acts on an object. Which of the following best describes the object’s motion? The object is moving with a constant acceleration. The same net force is applied to two different objects.

## Why we never see objects continuing to move in a straight line indefinitely despite their inertia?

” In the absence of external forces, motion in a straight line and at constant speed continues indefinitely. ” … It resists being put in motion, and once moving, it resists just as much being slowed down or stopped. (In Newton’s day, of course, no one had any experience in moving “weightless” satellites in orbit.
