Question

define displacement .instantaneous acceleration .average velocity​

Answer 1

Explanation:

define displacement

The word displacement implies that an object has moved, or has been displaced. Displacement is defined to be the change in position of an object.

define .instantaneous

Instantaneous comes from the Latin instant- meaning "being at hand." When something is instantaneous, it's right at hand when you need it. You can produce an instantaneous reply to someone or see an instantaneous change happen. If something happens very suddenly, you can describe it as instantaneous.

define acceleration

Acceleration is the rate of change of velocity.

define average 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.

Displacement: In geometry and mechanics, a displacement is a vector whose length is the shortest distance from the initial to the final position of a point P undergoing motion.

Instantaneous acceleration: Instantaneous acceleration is the acceleration of the object at some discrete instant in time and can be found by taking the derivate of the velocity function. In other words, instantaneous acceleration, or simply acceleration, is the rate of change of velocity with respect to time.

Average velocity: The average velocity of an object is its total displacement divided by the total time taken. In other words, it is the rate at which an object changes its position from one place to another. Average velocity is a vector quantity. The SI unit is meters per second.
