Do you like inline skating?
Yes it is like roller skating right? 
yes, inline skates have two front and two rear wheels
LOL Yes I love it I just hate being at the skating rings with lots of others and fall.
You need to have rubber brake blocks attached to your skates in order to avoid falling.
Sometimes it has those but I still fall is there other safety tips I should know about?
Just be careful.  Rubber stop is the only think that I know.
That was very helpful thank you do you go out skating alot with your family or friends?
Inline skates
Inline skates are a type of roller skate used for inline skating. Unlike quad skates, which have two front and two rear wheels, inline skates typically have two to five wheels arranged in a single line. Some, especially those for recreation, have a rubber "stop" or "brake" block attached to the rear of one or occasionally both of the skates so that the skater can slow down or stop by leaning back on the foot with the brake skate.

Parts.
A skate is composed of a "boot," worn on the foot. To the boot is attached a "frame", which holds the "wheels" in place. "Bearings" allow the wheels to rotate freely around an axle. Finally, the rubber "brake" typically attaches to the frame of the right foot.
There are different types of inline skates for different types of skating such as aggressive skating, speed skating, inline hockey and artistic inline skating.
