Feet per second is a unit of velocity, but not necessarily the same thing. Velocity could be in meters per hour or feet per second could be a measure of speed, which does not take direction into account, as velocity does.

What is initial velocity measured in?
Initial velocity can be measured in the same units as any other velocity. In SI, that would be meters per second, but often km / hour are used, or (in a minority of countries) feet/second or miles/hour.
How do units for speed and velocity compare?
The units are the same (metres per second) except that the velocity also has the direction of motion associated with it.
If a rock is dropped from a 144ft building what is its velocity after one second?
After one second the rock will be traveling at 9.8m/s (meters per second) or 32.17 feet per second. The height of the building is irrevelant, because gravity always pulls with the same force of 9.8m/s2 (meters per second squared), which means that every second the velocity will increase by 9.8m/s. This is why after one second the rock will be going 9.8m/s.
How much is 19.44 linear feet in feet?
Linear feet and feet means the same thing.
What is the result if you subtract a velocity vector to another velocity vector?
The result will also be a velocity vector. Draw the first vector. From its tip draw the negative of the second vector ( ie a vector with the same magnitude but opposite direction). The the resultant would be the vector with the same starting point as the first vector and the same endpoint as the second. If the two vectors are equal but opposite, you end up with the null velocity vector.

How is speed acceleration and velocity the same?
Speed is the rate of change of position per unit time. The dimension is Length / Time. Common units are meters per second, miles per hour, feet per second. Velocity is nearly the same (same dimensions), except that velocity is a vector, meaning that it has direction as well.Now acceleration is the rate of change of velocity. It also is a vector. Its dimensions are Length/(time^2). Typical units are meters/sec^2 and feet/sec^2.
What is acceleration and velocity?
Acceleration and velocityVelocity - which is not quite the same thing as speed -- is the measure of the rate of change in position. In other words, to calculate velocity, we divide the change in an object's displacement -- how far it moved -- by the time it took to move. If an object moves, say, 100 feet in 10 seconds, its velocity is 100/10 = 10 feet per second (ft/s). Acceleration is the rate of change of velocity. If an object increases its speed from, say, 10 ft/s to 60 ft/s in five seconds, its acceleration is 10 feet per second per second, or 10 feet per second squared (ft/s2).How did we arrive at that figure? Divide the change in velocity by the change in time. The change in velocity is 60 - 10 = 50 ft/s. The change in time is 5 - 0 = 5 s. Hence, 50/5 = 10 ft/s2.
What is the speed velocity of a body?
In common speech, velocity means speed, they are the same thing.
Is constant speed and constant velocity the same thing?
No.
Are Speed and velocity the same thing?
No. Speed has no direction. Velocity is speed anddirection.
How speed affect the velocity?
Different words for same thing
Which describes an object and velocity that changes by the same amount each second?
An object with a constant acceleration will have its velocity change by the same amount each second. The acceleration remains constant, causing a uniform increase or decrease in velocity over time.
Why the units of velocity and speed are same?
because they measure different aspects of the same thing, velocity also has direction but speed lacks direction. otherwise they are the same.
Does an object have twice as much velocity if it has twice the mass of a second object?
No. An object's velocity is completely unrelated to its mass. When you're sitting in your seat on a commercial airliner cruising at 30,000 feet, your velocity is precisely the same as the airliner's velocity, even though, we venture to surmise, there is quite a difference between the airliner's mass and yours.
Is a velocity graph the same thing as an acceleration graph?
No, a velocity graph shows changes in an object's velocity over time, while an acceleration graph shows changes in an object's acceleration over time. Velocity is the rate of change of position, while acceleration is the rate of change of velocity.
What describe an objects velocity that changes by the same amount each second?
An object with velocity that changes by the same amount each second is undergoing constant acceleration. This means that its velocity is increasing or decreasing by a consistent rate over time. Mathematically, this can be represented by a linear relationship between velocity and time.
