ACCELERATION

Acceleration

In physics, acceleration is the rate at which the velocity of a body changes with time. Velocity and acceleration are vector quantities, with magnitude, direction, and add according to the parallelogram law. As described by Newton's Second Law, acceleration is caused by a net force; the force, as a vector, is equal to the product of the mass of the object being accelerated and the acceleration . The SI unit for acceleration is the metre per second squared .

acceleration

Noun

  1. The act of accelerating, or the state of being accelerated; increase of motion or action; as opposed to retardation or deceleration.
    a falling body moves toward the earth with an acceleration of velocity
  2. The amount by which a speed or velocity increases (and so a scalar quantity or a vector quantity).
    The boosters produce an acceleration of 20 metres per second per second.
  3. The change of velocity with respect to time (can include deceleration or changing direction).
