If you slide a hockey puck across a frictionless ice rink is there a horizontal force on it to keep it in motion?

Once contact with the object that provided the force to initiate the motion, i.e. your hand or the hockey stick, there is no force tending to keep it in motion. The inertia of the puck in motion will resist any change in that motion, but inertia is a physical property not a force. From a free body diagram the only apparent force acting on the puck would be air resistance tending to slow it down.

What law is a puck sliding uniformly across the ice at a hockey game?
Newton's First Law, commonly called the Law of Inertia:Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
If a hockey puck is set in motion across a frozen pond if ice friction plus air resistance are neglected the force required to keep the puck sliding at a constant velocity is?
If you have eliminated all resistance then the initial force will be enough.
Is there an analogy in across five Aprils?
no, it as no analogy just newton's first law of motion and hilter's suicide due to germany's loss
Why does a clock move in the opposite direction from the Moon and Earth?
Clocks developed in the Northern Hemisphere and most were designed to follow the same (clockwise) motion as appears on the earlier invention, the sundial. In the Northern Hemisphere, a horizontal sundial facing south will display the passage of time as motion west to east, as the Sun appears to move east to west.
Where do motion pictures come from?
motion pictures came from the bottom of the universe. they were created my thomas Edison and the dude that created the light bulb.. motion pictures are the same as film. film is better than motion pictures.
If you slide a hockey puck across a frictionless ice rink these must be a horizontal force on it too keep it in the motion?
F=ma constant speed would mean 'a' acceleration is zero thus force zero. The puck would be in equilibrium, and the force would be zero at constant motion. Constant motion is constant velocity including the constant zero velocity.
A hockey puck is sliding across a friction less surface what large force us needed?
No large force is needed for a hockey puck to slide across a frictionless surface. Once the puck is in motion, it will continue to move indefinitely without any additional force due to the absence of friction.
What forces act on a frictionless air puck as it moves across a table in a straight line?
The main force acting on a frictionless air puck moving in a straight line across a table is inertia, which keeps the puck in motion. Additionally, there may be forces like gravity and normal force acting on the puck, but these forces do not affect its horizontal motion since the table is assumed to be horizontal.
What plane of motion is horizontal extension in?
Horizontal extension is in the transverse plane of motion, which runs horizontally across the body from side to side. This movement involves extending the arms or legs outwards away from the midline of the body.
Motion perpendicular to earth's surface is what kind of motion?
Motion Perpendicular to the ground is called horizontal motion.
What is the amount of force needed to keep a ball moving that has been launched into frictionless space?
In the vacuum of frictionless space, no force is needed to keep the ball moving. According to Newton's First Law of Motion, an object in motion will stay in motion unless acted upon by an external force. Therefore, once the ball is launched into frictionless space, it will continue moving indefinitely.
If a cart is observed moving at a constant velocity along a horizontal frictionless track is there a constant net force acting on it in the direction of motion?
No force is acting on it. Constant velocity means no acceleration, which means no force, from f=ma, no 'a' no force.
What is frictionless in motion?
Frictionless motion describes a situation where there is no resistance or opposition to an object's movement. This can occur in idealized scenarios, such as in a vacuum or with certain lubricated surfaces, where friction is eliminated. In these cases, objects can continue moving indefinitely without the need for an external force to maintain their motion.
Is force different in a frictionless floor?
Yes, in a frictionless environment, there is no force opposing motion, so objects will continue to move at a constant velocity unless acted upon by an external force. This means that less force is required to maintain or change an object's motion on a frictionless floor compared to a floor with friction.
What are horizontal motion and vertical motion?
horizontal is side to side vertical is up and down
Why horizontal motion is constant?
Horizontal motion is constant when there are no external forces acting on an object in that direction. According to Newton's first law of motion, an object in motion will stay in motion at a constant velocity unless acted upon by an external force. This is why horizontal motion can remain constant when there is no acceleration or deceleration.
Does the horizontal motion affect the vertical motion of a projectile?
No, horizontal motion does not affect the vertical motion of a projectile. The two components of motion (horizontal and vertical) are independent of each other in the absence of external forces such as air resistance. The vertical motion is governed by gravity, while the horizontal motion remains constant.
