What forces act on the puck as it skids across the ice?
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 .
Is the hockey puck’s motion at a constant speed?
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 . A hockey puck slides on ice at constant velocity .
What force is required to keep it sliding at constant velocity?
It includes the law of inertia → if there is no force , F = 0, then the acceleration = 0 → the velocity doesn’t change → no force is needed to keep an object moving with constant velocity . If there is more than one force acting on an object, then F is the net force .
When any object is in mechanical equilibrium what can be correctly stated about all the forces that act on it must the net force necessarily be zero?
For an object to be in equilibrium , it must be experiencing no acceleration. This means that both the net force and the net torque on the object must be zero .
Would the path of the puck be straight or curved?
Do you think the released yo-yo’s path will be straight or curved ? Explain. It will curve because the yo yo is spinning. The Uniform Circular Motion Gizmo™ shows a pink puck that is floating above a circular air table.
Is air resistance a push or pull?
A force is a push or pull acting upon an object. There are eight different sorts of forces, one of the forces is air resistance . Air resistance force happens when air is pushing against a moving object. Air resistance is a kind of frictional force.
Why is an ice hockey puck given an initial push continue to move?
The wet ice provides a surface that is almost free of any horizontal influences that would slow down the puck , and so if the puck is given an initial push on such a surface, it will continue to coast at a constant velocity. The rate at which your velocity is changing with time.
Is any force acting on the puck now?
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 Newton’s second law apply to hockey?
Newton’s Second Law ( the law of force and acceleration) states that if the mass of an object remains the same, the acceleration will increase as the force increases. In hockey , during a slapshot, the puck’s mass remains the same but the acceleration increases as the force the player applies to the puck increases.
What is the force at constant velocity?
If a body is moving with constant velocity, acceleration is zero. So net force acting on it will be also zero. But the body has energy due to its constant motion .
Does constant velocity mean no acceleration?
An object with a constant acceleration should not be confused with an object with a constant velocity . If an object is changing its velocity -whether by a constant amount or a varying amount – then it is an accelerating object. And an object with a constant velocity is not accelerating .
Does constant speed mean constant velocity?
To summarize, an object moving in uniform circular motion is moving around the perimeter of the circle with a constant speed . While the speed of the object is constant , its velocity is changing. Velocity , being a vector, has a constant magnitude but a changing direction.
What are the three conditions of equilibrium?
A solid body submitted to three forces whose lines of action are not parallel is in equilibrium if the three following conditions apply : The lines of action are coplanar (in the same plane) The lines of action are convergent (they cross at the same point) The vector sum of these forces is equal to the zero vector.
What are the 3 types of equilibrium?
There are three types of equilibrium : stable, unstable, and neutral. Figures throughout this module illustrate various examples. Figure 1 presents a balanced system, such as the toy doll on the man’s hand, which has its center of gravity (cg) directly over the pivot, so that the torque of the total weight is zero.
What are the two conditions of equilibrium?
For an object to remain in equilibrium , two conditions must be satisfied – both the net force and the net torque must be equal to zero. An example of an object in equilibrium is a rod that is free to rotate about a hinge at one end.
