Acceleration is the rate of change of velocity. At any point on a trajectory, the magnitude of the acceleration is given by the rate of change of velocity in both magnitude and direction at that point. The true acceleration at time t is found in the limit as time interval Δt → 0 of Δv/Δt.
Peak acceleration experienced by cosmonauts during the Soyuz 18a abort [9] 333 m/s 2: 34 g: Peak deceleration of the Stardust Sample Return Capsule on reentry to Earth [10] 454 m/s 2: 46.2 g: Maximum acceleration a human has survived on a rocket sled [3] > 491 m/s 2 > 50 g: Death or serious injury likely [citation needed] 982 m/s 2: 100 g ...
Consequently, the acceleration is the second derivative of position, [7] often written . Position, when thought of as a displacement from an origin point, is a vector: a quantity with both magnitude and direction. [9]: 1 Velocity and acceleration are vector quantities as well. The mathematical tools of vector algebra provide the means to ...

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 = = =.
An acceleration clause is a section of a mortgage contract that can have big consequences: Namely, it can require you to pay off your entire mortgage at once. Even if you miss only one payment.
The Atwood machine (or Atwood's machine) was invented in 1784 by the English mathematician George Atwood as a laboratory experiment to verify the mechanical laws of motion with constant acceleration. Atwood's machine is a common classroom demonstration used to illustrate principles of classical mechanics .
