# When the net force that acts on a hockey puck is 10n the puck? If a net force 6F is applied to an object with mass 2m, what is the acceleration on this object? When the net force that acts on a hockey puck is 10N, the puck accelerates at a rate of 50 m/s2.

Beside the above, when the net force that acts on a hockey puck is 12 N? When the net force that acts on a hockey puck is 12 N, the puck accelerates at a rate of 48 m/s2 48 m / s 2 .

Moreover, what is the net force of a hockey puck? What is the net force acting on the puck? 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.

Also the question is, what forces act on a hockey puck? Bookmark this question. Show activity on this post. 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.

Furthermore, how do you calculate the net of forces acting on an object? Net force is the sum of all forces acting on an object. The net force can be calculated using Newton’s second law, which states that F = ma, where: F is the net force. m is the mass of the object.The net work done by all forces acting on an object is equal to the kinetic energy change of that object. If the net work is zero, that means there is no kinetic energy change.

## Which statement explains why a book resting on a table is in equilibrium?

Which statement explains why a book resting on a table is in equilibrium? The weight of the book equals the weight of the table.

## What force causes the puck to move in a circle?

Centripetal force is, simply, the force that causes centripetal acceleration. Objects that move in uniform circular motion all have an acceleration toward the center of the circle and therefore, they must also suffer a force toward the center of the circle. That force is the centripetal force.

## 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.

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

A hockey puck slides across the ice at a constant speed. Is it in equilibrium? Why or why not? Yes, because it reaches dynamic equilibrium when it moves in a straight line with unchanging speed.

## What forces are used in hockey?

As the hockey player pushes off with his rear leg, a perpendicular force F is exerted on the skate by the ice. The component of the force F that points forward (in the direction of motion) is what pushes the player forward. At the same time, his other skate is either raised or gliding on the ice.

## How hard does a hockey puck hit?

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. There is nothing unusual about the speed, since golf balls, tennis balls, and baseballs can also be projected at that speed or even higher. 1.

## What happens to the kinetic energy of a hockey puck as it moves across the ice and is stopped by a hockey stick?

Friction causes kinetic energy to transfer into thermal energy—as the kinetic energy decreases, so does velocity.

## What is net force equation?

Fa = Applied force and. Fg = Gravitational force. Net force is when a body is in motion and many forces are active on it like gravitational force Fg, frictional force Ff, and the normal force. Therefore, the net force formula is given by. FNet = Fa + Fg + Ff + FN.

## What represents net force?

The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.

## How do you find net force with two forces?

If two(or more) forces act on an object in the same direction, the net force is the sum of the forces.

## How much work is done by the net force?

Key Points. The work W done by the net force on a particle equals the change in the particle’s kinetic energy KE: W=ΔKE=12mv2f−12mv2i W = Δ KE = 1 2 mv f 2 − 1 2 mv i 2 .

## What does a net work of 0 mean?

When the net force acting on an object is zero, the net work done by all the forces acting on the object is zero.

## How is the net work related to force and displacement?

Net work is defined to be the sum of work done by all external forces—that is, net work is the work done by the net external force Fnet. In equation form, this is Wnet = Fnetd cos θ where θ is the angle between the force vector and the displacement vector.

## In which situation is the net force on the object equal to zero?

If the net force on an object is zero, then the object is in equilibrium. It means the sum of the forces in all directions must be equal to zero.

## When the sum of forces on an object is zero the object?

Newton’s first law states that when the vector sum of all forces acting on an object (the net force) is zero, the object is in equilibrium. If the object is initially at rest, it remains at rest. If it is initially in motion, it continues to move with constant velocity.

## When the sum of all the forces acting on an inclined plane is zero the block?

There is a block on an inclined plane and the force The summer forces on this block is zero. The question of forces actually mass multiplied by acceleration If force is zero it means that the acceleration On the body zero because mass cannot be zero. So there is no acceleration or no negative acceleration.

## What is the force causing the centripetal acceleration of the puck?

Now the centripetal acceleration always acts towards the center, and in this direction there is only one force which is the tension force. Therefore the correct option would be B that is the tension force in the strength produces the centripetal acceleration.

## What is the direction of the force on the puck as it travels in a circle and how do you you know?

The net force acting upon such an object is directed towards the center of the circle. The net force is said to be an inward or centripetal force. Without such an inward force, an object would continue in a straight line, never deviating from its direction.

## Is the direction of net force always in the direction of motion?

While the net force may not be in the same direction which the object is moving, it is always in the direction that the object is accelerating. So if the acceleration is centripetal, then so is the net force.

## When the puck is dropped the potential energy will be?

When the puck is dropped, the potential energy will be equal (=) to the kinetic energy when it lands.

## How does temperature affect a hockey puck?

Hockey pucks are frozen to make them more solid and to reduce bouncing. Pucks are made from vulcanized rubber and the warmer they are the more they’ll bounce when whacked with a stick.

## How many forces act on a hockey puck sliding at constant velocity?

Note that the force is indicted with a thick arrow and the velocity with a thin one. (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 is physics related to hockey?

When a player flexes, or bends, his stick, energy is stored in the blade. As a player makes contact with the puck during a slap shot, he shifts his weight and flicks his wrists. This rotation causes the stored energy to release off of his stick and transfer to the puck.

## What is the science of hockey?

The overall motion of the shooter combined with the stick snapping back into place releases energy into the puck. A slight snap of the wrists at the end of the motion allows the puck to spin, which allows the puck to sail through the air in a stable trajectory, helping the shot’s accuracy.

## How fast is a puck shot?

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. There is nothing unusual about the speed, since golf balls, tennis balls, and baseballs can also be projected at that speed or even higher.

## How fast is the average puck shot?

The average speed of Slap Shots in the NHL today is right around 100 miles per hour, compared to 10 seasons ago where the average was around the low 90’s!

## What forces act on a puck?

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 is the change in the kinetic energy of the puck?

During this act kinetic energy in the puck transforms into thermal energy as a result of friction.
