Snap, [6] or jounce, [2] is the fourth derivative of the position vector with respect to time, or the rate of change of the jerk with respect to time. [4] Equivalently, it is the second derivative of acceleration or the third derivative of velocity, and is defined by any of the following equivalent expressions: = ȷ = = =.
In mechanical engineering, jerk, in addition to velocity and acceleration, is considered in the development of cam profiles because of tribological implications and the ability of the actuated body to follow the cam profile without chatter. [11] Jerk is often considered when vibration is a concern. A device that measures jerk is called a ...
In certain sports, a magic number is a number used to indicate how close a front-running team is to clinching a division title and/or a playoff spot. It represents the total of additional wins by the front-running team or additional losses (or any combination thereof) by the rival teams after which it is mathematically impossible for the rival teams to capture the title in the remaining number ...
Whenever the rate of change f′ of a quantity f is proportional to the displacement of an object, the quantity f is a linear function of the object's absement. For example, when the fuel flow rate is proportional to the position of the throttle lever, then the total amount of fuel consumed is proportional to the lever's absement.
All parameters correctly handle plurals (1 win, 2 wins etc.). w - the number of wins; l - the number of losses; d - the number of draws; otl - the number of overtime losses; t - the number of ties (for use in sports, such as cricket, where draws and ties are different results) nr - the number of no result outcomes
Essentially, this treats each unplayed game as being a tie (i.e. 1 ⁄ 2 win and a 1 ⁄ 2 loss). In an extreme example, attempting to compare the records of the 2007 New England Patriots (16–0; 1.000 winning percentage) [ 1 ] and the 1972 Detroit Tigers (86–70; .551 winning percentage) [ 2 ] finds that the teams are equivalent on a games ...
For example, if a team's season record is 30 wins and 20 losses, the winning percentage would be 60% or 0.600: % = % If a team's season record is 30–15–5 (i.e. it has won thirty games, lost fifteen and tied five times), and if the five tie games are counted as 2 1 ⁄ 2 wins, then the team has an adjusted record of 32 1 ⁄ 2 wins, resulting in a 65% or .650 winning percentage for the ...
The game shall be commenced by a place kick from the centre of the ground by the side losing the toss, the other side shall not approach within 10 yards of the ball until it is kicked off". A "place kick" is further defined as "a kick at the ball while on the ground, in any position in which the kicker may choose to place it".
