Pour sand over the ice.
Reduce friction or increase slope.
you could place salt on the icy areas to increase friction because the ice would began to melt.
you can get old piece of wood
add or remove lube
Actually, waxing skis increases friction. Wax is not slippery. If you wanted less friction you could oil your skis.
i believe the answer would be friction. friction, acting in opposition to the motion of the ball
Yes, it should be. If the sidewalk is not higher than the lawn water will collect on top of the sidewalk when it rains. If the temperature drops below freezing the sidewalk could crack.
You can wear rubber based items You can add salt to surfaces You can roughen the surface. Hope this is useful! : )
The driver could use different sized tires or reduce the amount of friction.
With any moving fluid, there will be a little bit of friction, which would increase temperature. But the heat could be dissipated to the surroundings just as fast as the friction is generating the heat, depending on the type of fluid, speed, and configuration of the pipe. For your question - the faster the flow, the more friction and therefore heat.
There is more friction between the surfaces of 2 smooth surfaces than one smooth surface because there is more surface area.
Friction is decreased by means of lubrication.
