The resistance to a change in velocity is called "inertia". It is related to the mass of an object.

What do you call it when an objects velocity changes?
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.
What describes an object and speed and direction?
As regards a moving object, we call the measure of the speed and direction it is moving its velocity.
A 2kg is dropper from a height of 1000m what is the force of air resistance on the obhect when it raches terminal velocity?
When it reaches terminal velocity it is not accelerating. According to newton's 2nd law, if acceleration = 0, then Net force = 0 If we call up to be positive direction Net force = -mg + Force air resistance = 0 So the air resistance force would be equal in magnitude to m*g and opposite in direction. m is mass of object, g is about 9.81 for objects near earths surface
What is called speed of an object at a given instant?
An objects speed at any particular moment in time is known as its instantaneous velocity. This is the rate of change or the derivative of the objects position.
The car rounds the turn at a constant velocity of 90 mph?
If the car rounds the turn, then its velocity is not constant.Velocity is a thing that has magnitude and direction. The magnitude is what we call "speed".If the direction is changing, then the velocity is changing, even if the speed is constant.

What do you call speed in a given direction?
Speed in a given direction is velocity.
What is it call when you know both speed and direction?
"velocity"
What describes an object and speed and direction?

What do you call the speed over time?
As long as direction doesn't change, speed over time is called acceleration.
Can a speed of a body be negative?
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.

Is Velocity is an example of a vector?
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".
How do you call the distance an object travels in a unit of time?
'Speed' . If you also specify the direction in which it moves by that distance, then you have 'velocity'.
Does velocity have to be represented by north east etc?
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.
