Who knows and who cares
depending if you mean field or ice hockey or even street hockey depends if you are versing a ball or a puck but i will assume you mean field. A hockey stick, shin guards and the keepers gloves are all the objets allowed to legally make contact with the ball. naturally the ball will fly up a bit and hit bodies/head but actively if is just these and really should only be the stick.
It means nothing in field hockey.
a ball is flicked in the air and travels
its where you loose your virginity to a donkey.
Legitimately prevent the ball from passing over the goalline beneath the crossbar. this might mean deflecting it with your stick, goalkeeper's pads or body, or trap it and clear it away from the goal.
Maybe field hockey? I don't know exactly what you mean.....
In soccer, it means to legally catch the ball with your body. In Field Hockey, trapping is catching the ball by pinning it between the stick and the ground, after which the player can move with the ball. In US football, it means that a forward pass is ruled incomplete because the player did not cleanly catch the pass, but caught it between his body and the ground.
Square ball usually means a horizontal pass; that is, a pass that goes along or near a path parallel to the backlines/centreline.
Depending on the sport, where the players were, who had the ball, and what else was happening at the time, possibly. For most sports, being in possession in a certain part of the field (field hockey, football) or when taking a shot (basketball) can mean you get a free shot as penalty.
The 'Lift' is legal when executed properly and only if it does not cause danger to the opposing player. lift's are usually used to push the ball or lift the ball over a players stick in order to beat the player and get passed them to gain ground or an advantage.
Field hockey balls are commonly white; this is the requirement for international matches. Other grades may use orange, and practise balls can be obtained that are white, yellow, orange, pink, purple and several other colours. An ice or road hockey ball is typically high-visibility orange.
