The rate of change of velocity with respect to time.
Acceleration is a vector quantity.
Acceleration is related to the force on an object and its mass by Newton's second law, stating that acceleration equals force divided by mass. The frequency of a periodic system , multiplied by 2 p . A dynamical system in which no energy is either lost or gained by the system. These are systems where friction is negligible. In a right triangle, the ratio of the adjacent side to the hypotenuse.
