yes
Three bad things about doing gymnastics are,Risk of injuryStressPassing/concussions
bad friction is when 2 things rub together .
Friction isn't always bad, but when engineers try to avoid or reduce friction, it is because of the energy lost due to friction.
Yes
friction in gymnastics is hanging on bars. they rub chalk so there hands are rough and they get good grip.
Friction is good because it provides traction. Friction is necessary for people to stand, or for vehicles to accelerate or break. Friction can also be used to convert kinetic energy to heat or electrical energy. Friction can be bad because kinetic energy is can be lost to friction.
