When you push a skateboard on a flat surface why does it stop after a while?

Several reasons. The main reason being the friction created by the gravitation force acting on the board and pushing the wheels to the ground. Also the air resistance as the board is moving forward. Thirdly, the surface in which the skateboard is riding on would need to be perfectly smooth, theoretically on air, to create no resistance. And finally the rotation of the wheels against the bearings creates friction which even though they are greased to reduce the friction can not completely eliminate this factor.

Is a cube aerodynamic?
No, a cube is not aerodynamic. A cube has a flat face, so it will produce more drag. It will also take more energy to push forward because the flat face of the cube is trying to push the wind as you are pushing the cube.
What type of a simple machine is a push pin?
A push pin is a fastener. As a minimum, it fastens a very visible head to a surface. Even used symbolically on e.g. Google maps. Alternately it may fasten one surface (paper) to another.
Why some foam cubes get smaller in a syringe and some stay the same size?
Becausse ghe gas hass not a lot of pressure so it will push the cubes flat but the syringe isnt strong enogh to keepp them all flat
How do you calculate the volume of a nut?
One method would be with water displacement. Fill a graduated cylinder with a known amount of water. Drop in the nut. Push below surface with wire, or something with negligible volume. Read volume, and subtract.
What is the meaning of pull push rule?
Pull here push there rule men! :D
What makes a skateboard fast or slow?
the friction between the wheels and the surface of the ground affect the speed of the skateboard. fo instance if you ride the skateboard on a smooth surface (with less friction) the skateboard will go faster.
Will a manual car in neutral roll on a flat surface?
Only if you push it. On a perfectly flat surface, in neutral it will not roll without assistance.
What motions occur on a skateboard?
Kick, Push
If you stand on a skateboard and push off the ground with one of your feet the reason that the skateboard moves forward is that the force you apply to the skateboard equals what?
friction
How many people are required to push a 4000 lb vehicle on a flat surface?
60 people with anthropedimetric alkorotovetics can do it.
What is the differercne between folding and faulting?
A fault causes a crack due to one tectonic plate overlapping another like if you place 2 piles of books on a flat surface and push them together., A fold is like a bend, like if you place 2 towels on a flat surface and push them together.
What is the difference between thumbtack and push pin?
a thumb tack has a flat circle top while a push pin has the tower like top.
Does friction exist on a stationary object on a flat surface?
Yes. Otherwise, the slightest push would make the object move around.
If you stand next to a wall on a frictionless skateboard and push the wall with a force of 40 N how hard does the wall push on you?
40 newtons
If you ride a skateboard with your right foot in back and push of with your left is this normal and what is it called?
that is regular
How can a skateboard do what it does?
This is a mighty vague question, but I'll give it a shoot. A skateboard has wheels - when these wheels are acted upon by a force (such as you pushing it), they proceed to take the energy from that force and change it into centrifugal and centripetal forces- this causes the wheels on your skateboard to turn. Your skateboard won't roll indefinitely from 1 push because while your skateboard is rolling it is creating friction with the sidewalk you're skateboarding on. Friction is caused when 2 objects rub up against each other - this creates heat and a transfer of kinetic energy. Once all the kinetic energy has been transferred from your skateboard's wheels to the sidewalk, your skateboard come to a stop.
What are the forces act on a skateboard?
There are several forces involved while riding a skateboard. The force of friction (air resistance and contact with ground) acting against the motion and the pushing force from when you push off with your foot acting with motion. There are also several normal reaction forces, the weight of the person on the skateboard and the weight of the skateboard on the ground.
