Is it true that Velocity is the speed of the wave?
In common language, the terms "velocity" and "speed" are used interchangeably. In physics, "velocity" is a vector, and "speed" is not - meaning that when the word "velocity" is used, it specifies not just how fast something moves, but also in what direction.
Which of the following sets of measurements can be used to calculate acceleration?
change in time, initial velocity and final velocity
The difference in speed and velocity is that a measure of velocity must include?
In the study of kinematics, 'acceleration' means any change in the speed or direction of motion.
Does average velocity have a direction associated with it?
The term "velocity", as used in physics, DOES have an associated direction. Most derived terms, such as "average velocity", also do.
What formula is used to calculate accleration?
Accelaration= change in velocity/time taken OR Acceleration=final velocity- initial velocity/time taken
Can the words speed and velocity be used interchangeably?
yes. speed is velocity.
Is velocity speed?
As used in physics, the two are different. Speed is a scalar, velocity a vector.

What is the formula used to calculate the velocity of an object?
The average velocity in a particular direction = distance travelled in that direction / time taken. Velocity is a vector so the direction is important. If I go from A to B and then return to A my average velocity will be zero. My speed, on the other hand, will not be zero.
What two variables are used to caluate speed?
Speed=distance/time
Is speed the change in velocity?
No; the change in velocity over time is called acceleration.Speed and velocity are used interchangeably in popular language; in physics, the word "speed" is used for a scalar (that is, when the direction is irrelevant), and "velocity" is used for a vector (that is, when you need both a magnitude and a direction).No; the change in velocity over time is called acceleration.Speed and velocity are used interchangeably in popular language; in physics, the word "speed" is used for a scalar (that is, when the direction is irrelevant), and "velocity" is used for a vector (that is, when you need both a magnitude and a direction).No; the change in velocity over time is called acceleration.Speed and velocity are used interchangeably in popular language; in physics, the word "speed" is used for a scalar (that is, when the direction is irrelevant), and "velocity" is used for a vector (that is, when you need both a magnitude and a direction).No; the change in velocity over time is called acceleration.Speed and velocity are used interchangeably in popular language; in physics, the word "speed" is used for a scalar (that is, when the direction is irrelevant), and "velocity" is used for a vector (that is, when you need both a magnitude and a direction).
What equation is used to calculate the velocity of a fallin object?
(Initial downwards speed (m/s)) + (9.81m/s²)x(Time it has been falling(s)) = Downwards speed in metres per second.
What is a velocity report?
A velocity report is used to determine the speed at which products are sold at retail.
What formula is used to calculate accelation?
Change in velocity / time
Why is the absolute value of speed equal to velocity?
It's not. Unless you add a direction to speed it will not become velocity. Since positive and negative are sometimes used to denote direction, absolute value of velocity may equal speed (certain situations)
