[Answer] ____ is the rate of change in velocity.

Answer: Acceleration
____ is the rate of change in velocity.
The velocity of an object is the rate of change of its position with respect to a frame of reference and is a function of time. Velocity is equivalent to a specification of an object’s speed and direction of motion (e.g. 60 km/h to the north).
Velocity is a fundamental concept in kinematics the branch of classical mechanics that describes the motion of bodies. Velocity is a physical vector quantity ; both magnitude and direction are needed to define it. The scalar absolute value ( magnitude ) of velocity is called …
Velocity is a fundamental concept in kinematics the branch of classical mechanics that describes the motion of bodies. Velocity is a physical vector quantity ; both magnitude and direction are needed to define it. The scalar absolute value ( magnitude ) of velocity is called speed being a coherent derived unit whose quantity is measured in the SI ( metric system ) as metres per second (m/s) or as the SI base unit of (m⋅s ). For example “5 metres per second” is a scalar whereas “5 metres per second east” is a vector. If there is a change in speed direction or both then the object has a changing velocity and is said to be undergoing an acceleration .
Delta-v (more known as ” change in velocity “) symbolized as ∆v and pronounced delta-vee as used in spacecraft flight dynamics is a measure of the impulse per unit of spacecraft mass that is needed to perform a maneuver such as launching from or landing on a planet or moon or an in-space orbital maneuver.It is a scalar that has the units of speed.As used in this context it is …

In mechanics acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). The orientation of an object’s acceleration is given by the orientation of the net force acting on that object. The magnitude of an object’s acceleration as described by Newton’s Second Law is the combined effect of two causes: • the net balance of all external forces acting onto that object — …
