Its to do with constant values, the rate of acceleration refers to a constant change of velocity over time, so an acceleration of 10 (m/s)/s is a constant increase of velocity per unit time ( increase of 10 metres per second, every second )
Velocity is a constant increase in distance, per unit time (metres per second)

Does horizontal velocity effect the rate of vertical velocity?
No, horizontal velocity and vertical velocity are independent and have no effect on each other.
What is difference between vector field and the scalar field?
Look in the room that you are in. Its temperature varies at every point in the room. IN addition, notice that the air moves at different rates at each part of the room and therefore in different directions. The temperature is different at every point but it has no direction. It just has one value at each point in the room - temperature. On the other hand, the air is moving at different rates (velocity) around the room. Therefore it has a magnitude concerning the velocity. Unlike the temperature however, the air is also moving in a certain direction at each point. Therefore, at each point in space, the temperature is different and has only one value of magnitude so it is a scalar field. The air would be known as a vector field because in addition to its magnitude, its velocity, it has direction because it is moving.
What will happen to the momentum of a body whose velocity is doubled?
Momentum = mass x velocity. So if the velocity is doubled, momentum will be doubled as they are directly proportional to each other.
Can velocity and acceleration point in opposite direction?
Yes, velocity and acceleration can point in the opposite direction to each other. This is because neither one depends on the other. When velocity and acceleration are opposite each other this results in slowing down, for example when you hit the break on your car.
Can momentum have a negative velocity?
No, momentum can not have a negative velocity. Velocity is the rate of motion of a body from one position to another position in a particular direction. Bodies traveling in opposite directions may appear to have a negative velocity in relationship to each other but any amount of velocity is positive.
Does horizontal velocity effect the rate of vertical velocity?
No, horizontal velocity and vertical velocity are independent and have no effect on each other.
What is the escape velocity of the asteroid belt?
Each asteroid has its own escape velocity.
Why is wind considered a vector field?
At each point in space, the wind has a velocity, which is a vector. Another way of saying the same thing is that at each point, the wind blows at a certain speed and in a certain direction.
Explain the circumstances when the acceleration and the velocity of car are parallel?
when velocity of a car is increasing then velocity and acceleration are parallel to each other.
Are Speed and velocity the same thing?
No. Speed has no direction. Velocity is speed anddirection.
Explain how distance time and velocity are related to each other?
They are related through the formula distance = time x velocity (assuming constant velocity).

What would have a higher terminal velocity a marble or a napkin?
The marble has lower drag so its terminal velocity would be greater. Each has its own terminal velocity.
What is molecular velocity in chem?
Molecular velocity is defined as the velocity of a each molecule in a certain sample of gas. It can be expressed by means of root-mean-square velocity, average velocity and most probable velocity.
What will happen to the momentum of a body whose velocity is doubled?
Momentum = mass x velocity. So if the velocity is doubled, momentum will be doubled as they are directly proportional to each other.
How velocity modulation and density modulation related to each other?
due to velocity modulation density modulation occurs in TWT
Why modal dispersion limits the fiber bandwidth?
In a multimode fiber modal dispersion causes each mode to have a different velocity and reach to the end of the fiber at a different time. This will cause inter-symbol interference (ISI) which means that we need to send data at lower rates in order to prevent ISI. Lower rates means a reduction in bandwidth.
