Acceleration, it can be both increase and decrease in speed. .
the object's "speed"
Acceleration.
That is called the object's 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 a velocity.
A change in position in a certain amount of time is called motion.
the object's "speed"
Acceleration.
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.
Speed is the rate of change of distance with time. Velocity is the rate of change of displacement with time.
That is called the object's speed.
Velocity
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 a velocity.
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.

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".
