    =Energy=

K = (1/2)mv²

Kinetic activity is according to one-half of accumulation times the aboveboard of velocity.

K = (1/2)Iω²

Kinetic activity is according to one-half of moment of apathy times the aboveboard of angular velocity.

U_g = mgh

Potential activity due to force is according to the artefact of mass, dispatch due to gravity, and acme (elevation) of the object.

    U_e = (1/2)kΔx²

    Potential activity due to bounce anamorphosis is according to one-half the artefact of the bounce connected times the aboveboard of the change in breadth of the spring.

Variables

    K: Active activity (J)

    m: accumulation (kg)

    v: acceleration (m/s)

    I: moment of inertia, (kg·m²)

    ω: (omega) angular drive (rad/s)

    U_g: Abeyant activity (J)

    g: bounded dispatch due to force (on the earth’s surface, 9.8 m/s²)

    h: acme of acclivity (m)

    U_e: Abeyant activity (J)

    k: bounce connected (N/m)

    Δx: change in breadth of bounce (m)

Definition of terms

    Energy: a apparently ambiguous abundance that describes abeyant to do work. SI assemblage for activity is the joule (J). Aswell accepted is the calorie (cal).

    The joule: authentic as the activity bare to advance with the force of one newton over the ambit of one meter. Agnate to one newton-meter (N·m) or one watt-second (W·s).

    :1 joule = 1 J = 1 newton • 1 beat = 1 watt • 1 second

    Energy comes in some varieties, including Active energy, Abeyant energy, and Calefaction energy.

    Kinetic activity (K): The activity that an item has due to its motion. Bisected of acceleration boxlike times mass. Units: joules (J)

    Potential activity due to force (U_G): The activity that an item has stored in it by acclivity from a mass, such as aloft aloft the apparent of the earth. This activity is appear if the item becomes chargeless to move. Accumulation times acme time dispatch due to gravity. Units: joules (J)

    Potential activity due to bounce compression (U_E): Activity stored in bounce if it is compressed. Units: joules (J)

    Heat activity (Q): Units: joules (J)

    Spring compression (D_x): The aberration in breadth amid the bounce at blow and the bounce if continued or compressed. Units: meters (m)

    Spring connected (k): a connected specific to anniversary spring, which describes its “springiness”, or how abundant plan is bare to abbreviate the spring. Units: newtons per beat (N/m)

    Change in bounce breadth (Δx): The ambit amid the at-rest breadth of the bounce bare the aeroembolism or continued breadth of the spring. Units: meters (m)

    Moment of apathy (I): Describes accumulation and its distribution. (kg•m²)

    Angular drive (ω): Angular acceleration times accumulation (inertia). (rad/s)
