A fluid flowing past the surface of a body exerts a force on it. Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is the component of the surface force parallel to the flow direction. If the fluid is air, the force is called an aerodynamic force. In water, it is called a hydrodynamic force.

Lift or LIFT may refer to:

Lift is a range of soft drinks produced by The Coca-Cola Company that has been available in Australia, New Zealand, Latin America, Germany, Austria, and Eastern Europe since the 1970s, which is carbonated and flavored with fruit juice.

Lift is the sixth studio album by Christian rock band Audio Adrenaline.

Lift, released in 2004, is Sister Hazel's fifth studio album.

Lift is the seventh and final studio album by English alternative rock band Love and Rockets, released in 1998 on Red Ant Records.

"Lift" is the second single by Australian singer Shannon Noll from his second album of the same name. The boxing-themed video clip for this song was shot in an unused warehouse in Sydney's Marrickville by Australian director Anthony Rose, who also directed Noll's music videos for " Drive", " What About Me" and " Shine".

It debuted at number thirteen during the Christmas season and in its fourth week on the Australian Singles chart it peaked at number ten. Although the single was Noll's lowest charting at the time of release, sales of the single were very strong. The single became Noll's sixth single to reach Gold or Platinum sales, and also became his longest running Top 100 hit thus far.

The track has been used by various television productions as theme music. South African cricketer AB de Villiers and singer-songwriter Ampie du Preez covered the song on their album Maak Jou Drome Waar.

"Lift" is a song by the Finnish rock band Poets of the Fall. It is the second single released from their debut album, Signs of Life. The song was released in Finland on 9 September, 2004. The song reached #8 on the Finnish Top 40 and stayed there for 11 consecutive weeks. It contains two versions of the title track, as well as the B-side, The Beautiful Ones.

Markus Kaarlonen produced a dance remix of the song, entitled Lift (Dramadance Remix). It is only available for download (as an MP3 or WAV file) on a secret page of the band's official website which can be accessed by the special login and password from the Signs of Life album booklet.

Lift is a free and open-source web framework that is designed for the Scala programming language. It was originally created by David Pollak who was dissatisfied with certain aspects of the Ruby on Rails framework. Lift was launched as an open source project on February 26, 2007 under the Apache 2.0 license. A commercially popular web platform often cited as being developed using Lift is Foursquare.

Lift is a rock band formed in Dresden. The group was founded in 1973 and is still active today.

Lift is the second album by Australian singer-songwriter Shannon Noll. It was released by Sony BMG in Australia on 16 October 2005. Noll co-wrote eleven out of the thirteen songs in the album. The album debuted at number 1 on the Australian Recording Industry Association album chart on 23 October 2005 with a platinum certification and was eventually certified three times platinum. All four singles released from the album reached the Top 10 of the ARIA single chart, and proved to be very popular radio hits, with both " Shine" and " Now I Run" ending 2006 within the Top 10 most played songs on Australian radio.

Lift was nominated for "Best Pop Release" at the 2006 ARIA awards, the first industry voted nomination for any Australian Idol contestant. Further highlighting the longevity of Lift, the album ended 2005 as the 33rd biggest selling album in Australia and the 22nd biggest selling album in Australia of 2006.

In data mining and association rule learning, lift is a measure of the performance of a targeting model (association rule) at predicting or classifying cases as having an enhanced response (with respect to the population as a whole), measured against a random choice targeting model. A targeting model is doing a good job if the response within the target is much better than the average for the population as a whole. Lift is simply the ratio of these values: target response divided by average response.

For example, suppose a population has an average response rate of 5%, but a certain model (or rule) has identified a segment with a response rate of 20%. Then that segment would have a lift of 4.0 (20%/5%).

Typically, the modeller seeks to divide the population into quantiles, and rank the quantiles by lift. Organizations can then consider each quantile, and by weighing the predicted response rate (and associated financial benefit) against the cost, they can decide whether to market to that quantile or not.

Lift is analogous to information retrieval's average precision metric, if one treats the precision (fraction of the positives that are true positives) as the target response probability.

The lift curve can also be considered a variation on the receiver operating characteristic (ROC) curve, and is also known in econometrics as the Lorenz or power curve.

The difference between the lifts observed on two different subgroups is called the uplift. The subtraction of two lift curves forms the uplift curve, which is a metric used in uplift modelling.

It is important to note that in general marketing practice the term Lift is also defined as the difference in response rate between the treatment and control groups, indicating the causal impact of a marketing program (versus not having it as in the control group). As a result, "no lift" often means there is no statistically significant effect of the program. On top of this, uplift modelling is a predictive modeling technique to improve (up) lift over control.

In the branch of mathematics called category theory, given a morphism f from an object X to an object Y, and a morphism g from an object Z to Y, a lift (or lifting) of f to Z is a morphism h from X to Z that factors through g, i.e. g ∘ h = f.

A basic example in topology is lifting a path in one space to a path in a covering space. Consider, for instance, mapping opposite points on a sphere to the same point, a continuous map from the sphere covering the projective plane. A path in the projective plane is a continuous map from the unit interval, [0,1]. We can lift such a path to the sphere by choosing one of the two sphere points mapping to the first point on the path, then maintain continuity. In this case, each of the two starting points forces a unique path on the sphere, the lift of the path in the projective plane. Thus in the category of topological spaces with continuous maps as morphisms, we have

$$\begin{align} f\colon& [0,1] \to \mathbb{RP}^2 , &\qquad&\text{(projective plane path)} \\ g\colon& S^2 \to \mathbb{RP}^2 , &\qquad&\text{(covering map)} \\ h\colon& [0,1] \to S^2 . &\qquad&\text{(sphere path)} \end{align}$$

Lifts are ubiquitous; for example, the definition of fibrations (see homotopy lifting property) and the valuative criteria of separated and proper maps of schemes are formulated in terms of existence and (in the last case) unicity of certain lifts.

Lift is a meteorological phenomenon used as an energy source by soaring aircraft and soaring birds. The most common human application of lift is in sport and recreation. The three air sports that use soaring flight are: gliding, hang gliding and paragliding.

Energy can be gained by using rising air from four sources:

• Thermals (where air rises due to heat),
• Ridge lift, where air is forced upwards by a slope,
• Wave lift, where a mountain produces a standing wave,
• Convergence, where two air masses meet

In dynamic soaring it is also possible to gain energy, though this uses differences in wind speeds rather than rising air.

LIFT is a national nonprofit dedicated to helping families break the cycle of poverty. By fostering relationships between low-income parents (members) and dedicated volunteers (advocates), LIFT helps families build the strong personal, social and financial foundations to secure immediate, critical needs and to achieve long-term goals and aspirations.

LIFT connects with families through four sites located in communities with some of the highest rates of concentrated poverty: Chicago, Los Angeles, New York and Washington, DC. Because this work cannot be done alone, LIFT focuses on building strong community collaborations with a wide range of local, regional and national partners to help ensure families receive the resources and support they need. Since LIFT’s founding, over 12,000 volunteers have served nearly 100,000 individuals and families.
