The rate at which an object changes position is called what?

A change in position in a certain amount of time is called motion.


Is the rate of change of an object?

the object's "speed"


The rate of change in an object's velocity is the object's what?

Acceleration.


Is the rate at which an object changes velocity?

No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.


What is the relationship of the object's speed to its velocity?

Speed is the rate of change of distance with time. Velocity is the rate of change of displacement with time.


What is the rate an object covers distance in a paticular direction?

That is called the object's speed.


The rate at which an object moves is called?

Velocity


Is motion the change in speed?

no motion is the movement itself, the change in position of an object with respect to time. rate of change of speed is acceleration. change in speed is just change in speed.


The rate of change of displacement is called?

The rate of change of displacement is called a velocity.


When does the speed of an object change?

An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes. Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.

What describes the rate at which an object moves?

The rate at which an object covers distance is called the object's "speed".If the direction of its motion is also stated, then you have the object's"velocity".
