The disc will slow down as a result of the friction applied by the force.
force?
Well it's obviously not flying.
yes it is
In free space or on a frictionless surface, it takes no force to move something. Where there is friction, the ratio of (force necessary to start it moving horizontally)/(the object's weight) is the coefficient of static friction on the horizontal surface.
If the surface is smooth then it is almost frictionless. Hence the body will continue to move with constant velocity. However the object continues in a circular path and the weight is thus the centripetal force. It is assumed that the surface is very large)
No there is always a resistive force such as air resistance. The closest frictionless train is the japanese magnetic train which has no friction on the track.
The Horizontal Component of the normal force.
9.8 meters (32.2 feet) per second2 horizontally, provided the exercise is performed on or near the Earth.
Yes. The force is measured as "acceleration" and is meters per second per second (or velocity per second) or the first derivative of velocity. On a frictionless surface in an environment without air resistance, and if the skateboard is a frictionless mechanism, if the skateboard is moving at a constant velocity, that means the acceleration is zero, which means that there is no force being applied to it and it is a body in motion staying in motion.
Application of force lowers the melting point and thus the ice will melt.
By having a force act on that person.
If you are in a frictionless room, you can't push off of anything to exert enough force to move away. However, if you have a bottle of compressed gas or liquid, the force of the escaping gas from the container will exert a reaction force to push you where you need to go. If you are near a wall, you can push off of that.
