  2. Volleyball spiking - Wikipedia

    en.wikipedia.org/wiki/Volleyball_spiking

    The basic type of spike which, following the jump, the player draws the preferred hitting arm back, and the other arm pointing up, similar to a cocked bow. [3] This is followed by a whip-like action of the hitting arm, striking the ball with the hand at full extension. This spike keeps the elbow above the shoulder throughout the entire swing.

    en.wikipedia.org/wiki/Volleyball_Offensive_Systems

    Volleyball offense is how a team can attempt to score a point by causing the ball to land on the opposing teams side of the court.Generally, this is done by first receiving the ball from the other side in the form of either an attack or serve, having the ball set to an attacker, and then having a player jump and attack the ball.

    The maneuver involves digging the ball with the bottom hand and then directing it with the upper hand; J-Stroke : an emergency play made either running or diving, often with one hand, where a player has to reach well in front of themself to contact the ball and follow through in a 'J' motion in order to send the ball back over their head

  5. List of electromagnetism equations - Wikipedia

    The definitions for monopoles are of theoretical interest, although real magnetic dipoles can be described using pole strengths. There are two possible units for monopole strength, Wb (Weber) and A m (Ampere metre). Dimensional analysis shows that magnetic charges relate by q m (Wb) = μ 0 q m (Am).

  6. Magnetic field - Wikipedia

    For that reason a magnetic field measurement (by itself) cannot distinguish whether there is a positive charge moving to the right or a negative charge moving to the left. (Both of these cases produce the same current.) On the other hand, a magnetic field combined with an electric field can distinguish between these, see Hall effect below.

  9. Hall effect sensor - Wikipedia

    en.wikipedia.org/wiki/Hall_effect_sensor

    A radial magnetic field established by magnets on the thruster is used to trap electrons which then orbit and create an electric field due to the Hall effect. A large potential is established between the end of the thruster where neutral propellant is fed, and the part where electrons are produced; so, electrons trapped in the magnetic field ...
