Question

question 6
which statement best describes acceleration?
acceleration is the rate of change of position of an object.
acceleration is the rate of change of velocity of an object.
acceleration is the rate of change of force of an object.
acceleration is the rate of change of the direction of an object.

Explanation:

Acceleration is defined as the rate of change of velocity. Velocity is a vector quantity (has both magnitude and direction). When an object's velocity changes (either in magnitude, direction, or both), it is accelerating. The rate of change of position is velocity. Force is related to acceleration by \(F = ma\) (Newton's second law), but acceleration is not the rate of change of force. And just the rate of change of direction alone (if speed is constant) is a type of acceleration (centripetal acceleration), but the general definition is the rate of change of velocity.

Answer:

Acceleration is the rate of change of velocity of an object.
