(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.
You asked, what forces would be acting on a hockey puck while sliding across the ice? Question: 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.
People ask also, 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.
Similarly, what force is responsible for slowing down a hockey puck as it slides across the ice? An object sliding across a table or floor slows down due to the net force of friction acting on the object.
Likewise, 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 acceleration of the puck?
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 does a hockey puck slide?
How does Newton’s third law apply to hockey?
Newton’s Third Law (or the law of reaction) states that for every action force there is an equal and opposite reaction force. In hockey, many players will check the player that has the puck.
Which body exerts the force that propels the sprinter the blocks or the sprinter?
Which body exerts the force that propels the sprinter, the blocks or the sprinter? To start moving forward, sprinters push backward on the starting blocks with their feet. As a reaction, the blocks push forward on their feet with a force of the same magnitude. This external force accelerates the sprinter forward.
Is it correct to say that no force acts on a body at rest?
No force acts on a body at rest; if at least one force acted on it the body would move. … No net force acts on a body at rest; when the net force is zero, the body is in static equilibrium.
When no forces act on moving objects their paths are normally?
straight lines. When no forces act on moving objects their paths are normally straight lines.
Why does a hockey puck slow down?
Friction is the loss of kinetic energy into thermal energy, which is why the block slows down.
What is the body will remain at rest or move at constant velocity?
The property of a body to remain at rest or to remain in motion with constant velocity is called inertia. Newton’s first law is often called the law of inertia. As we know from experience, some objects have more inertia than others.
How is friction reduced between an air hockey puck and the table?
The air hockey table has raised edges that allow the puck to reflect off horizontally, and a very smooth, slippery surface that further reduces friction by suspending the puck on thin cushion of air ejected from tiny vent holes built inside the surface.
