The resistance to a change in velocity is called "inertia". It is related to the mass of an object.
Objects that provide resistance are often referred to as obstacles, hindrances, or impediments. These objects can impede progress or hinder movement.
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
As regards a moving object, we call the measure of the speed and direction it is moving its velocity.
Those objects are called reflectors. They bounce light rays back in the direction from which they came.
The rate at which a body moves is called its speed or velocity. Speed is the distance traveled per unit of time, while velocity includes both speed and direction.
Speed in a given direction is velocity.

"velocity"
As regards a moving object, we call the measure of the speed and direction it is moving its velocity.
Those objects are called reflectors. They bounce light rays back in the direction from which they came.
As long as direction doesn't change, speed over time is called acceleration.
The 'speed' of a body cannot be negative. But if you are stating the 'velocity' then it can be negative. Negative velocity means it is going opposite to the direction that you decided to call the positive direction.
Yes. If you are interested only in the magnitude (scalar quantity), you call it "speed"; if you are interested in the vector (magnitude and direction), you call it "velocity".
'Speed' . If you also specify the direction in which it moves by that distance, then you have 'velocity'.
If you call it "velocity" then you have to tell what direction it points.If you only tell how fast it is but you don't tell the direction, then it's "speed", not velocity.
sew is something you do to fix clothing needle and thread when you use these 3 objects people call it sewing !
