carpet... the lino allows things to slide across it easily, creating minimal friction. the carpet has hairs which catch on things and generates a large amount of friction.
lubricant!
if there was no friction on a slide, you would gain speed and slide off and depending on the slide (such as a water slide) kill yourself. too much friction makes it boring.
Gravity.
One of the things you could do is you could put soap and water on the slide.
The purpose of heat fixing the bacteria to the slide is so during the gram staining procedure the bacteria doesn't wash off. If you didn't heat fix the bacteria to the slide, it would not stay on the slide.
things slide on ice easily because the friction of them sliding melts a tiny layer of ice into water, "lubricating" them. Skaters slide on ice so easily because the metal skates cut into the ice, providing traction, which stops them from slipping and falling. They arrange their feet in a "V" and push left and right with their feet. Since the skates want to keep moving in a straight line, the skater goes forward, as well as their feet spreading apart.

smear will be washed( no smear will be left on the slide)
Without more information your question can not be answered. There are many "slide" things.
Adding a slide to a presentation could be easily made. Adding a slide could be by right-clicking and New slide option.
it makes the slide look more professional
When one wants things to slide, move, or turn easily.
It will depend on the friction. A building brick - approximately a rectangular prism - does not slide easily.
penguins can slide on ice.

Calcium promotes bone and teeth health which makes them stronger and not break as easily.
