# What is the net force on a hockey puck that is freely sliding across frictionless ice?

Contents

## 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.

## What is the net force acting on a hockey puck sliding on the ice at constant velocity?

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.

## 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.

## 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.

## Are the net force on an object and the acceleration of the object directly proportional?

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

## How does a hockey puck slide?

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.

## What do you know about the forces on the hockey puck as it slides across the ice at a constant speed?

A hockey puck slides across the ice at a constant speed. Is it in equilibrium? … Yes, because it reaches dynamic equilibrium when it moves in a straight line with unchanging speed. The net forces are zero.

## What is the net force acting on an object in equilibrium?

The vector sum of all of the forces acting on a body is a single force called the net force . If the net force is equal to zero, the object is said to be in equilibrium.

## How you can tell when an object is being acted on by a net force?

The net force on an object is the combined effect (the sum) of all the pushing and pulling forces actually acting on the object. If the forces pushing or pulling on an object are not balanced (a net force acts) then the object will accelerate in the direction of the net force.

## What is the net force acting on the box?

The force that is “left over” after all of the forces acting on an object are cancelled and/or combined is called the net force. A 3 N force and a 7 N force act in the same direction on a box.

## What is net force formula?

Formula of Net Force

When the body is at rest, the net force formula is given by, FNet = Fa + Fg. … When a force is applied to the body, not only is the applied force acting, there are many other forces like gravitational force Fg, frictional force Ff and the normal force that balances the other force.

## What is the horizontal force acting on the puck?

The same string is used to tie the puck hence the horizontal force is equal to the tension force. Thus, the horizontal force is 15.5N .

## How much force is required to keep a hockey puck in motion?

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. (Some force was required to get the puck to move in the first place, but that is a different matter). 2.

## What is the net force acting on an insect falling downward at a constant velocity?

We are required to apply Newton’s law of motion to an object moving at a constant velocity. An object moving at constant velocity has zero acceleration. A) zero. The net force acting on an insect falling downward at constant velocity is zero.

## When a rifle is fired How does the size of the force?

“When a rifle shoots a bullet, Newton’s Third Law says that the force that the rifle exerts on the bullet is exactly the same size as the force that the bullet exerts on the rifle – yet the bullet gets a much greater acceleration than the rifle.
