  • 1

    is where an object is in space and can be express being a distance from a reference point in meters.

    position

  • 2

    is the change in position per unit time.

    velocity

  • 3

    is the change in velocity per unit time.

    acceleration

  • 4

    is a scalar quantity.

    distance

  • 5

    is a vector quantity.

    displacement

  • 6

    Δx of a particle is defined as its change in position in some time interval.

    displacement

  • 7

    is also a vector quantity.

    displacement

  • 8

    is the length of a path followed by a particle.

    distance

  • 9

    is defined as the particle’s displacement Δx divided by the time interval Δt during which that displacement occurs:

    average velocity

  • 10

    is defined as the total distance d traveled divided by the total time interval required to travel that distance:

    average speed

  • 11

    is defined as the limit of the ratio Δx/Δt as Δt approaches zero. By definition, this limit equals the derivative of x with respect to t, or the time rate of change of the position:

    instantaneous velocity

  • 12

    is equal to the magnitude of its instantaneous velocity.

    instantaneous speed

  • 13

    is defined as the ratio of the change in its velocity Δ𝑣𝑥 divided by the time interval Δ𝑡 during which that change occurs:

    average acceleration

  • 14

    is equal to the limit of the ratio Δ𝑣𝑥 / Δ𝑡 as Δ𝑡 approaches 0. By definition, this limit equals the derivative of 𝑣𝑥 with respect to t, or the time rate of change of the velocity:

    instantaneous acceleration
