Which of the following must always be measured or described relative to something else?
motion
Why area is scalar?
Scalar quantities are described by a number alone, while vector quantities require a number and a direction, and as area cannot have an associated direction, must be scalar.
In velocity do you put the direction?
Yes, always. Velocity is a vector, meaning it has both a magnitude and a direction. You must account for the direction. Speed is the magnitude of velocity and has no direction.
Do vectors have direction?
Yes, vectors must have the direction. Without direction, it is simply a scalar quantity.
What is the definition of speed and the definition of velocity?
Speed is how fast something is going when the direction in which it is travelling is unimportant. Velocity is a measurement of the rate at which an object is changing its position. As such, in order to measure it, one must define both the speed at which an object is moving, and also the direction of movement.
What is something that must be described with both a size and a direction?
acceleration
What is Solar and vector quantities?
Vector quantities are those that must be described with both a magnitude and direction. Scalar quantities can be described with only a single value.

Is A force is a scalar quantity?
Force is a vector quantity. It has both magnitudeand direction.Let's look at a something and think about it. If you apply a force to something in an attempt to move it, the force will have to have direction associated with its magnitude. It must have direction. It doesn't make sense for force to not have direction. Gravity is a force of attraction between masses. A ball falls because the earth attracts it, and it falls down. That's the direction vector associated with gravity.
Why is an electric field strength a vector quantity?
for a vector quantity it must have both magnitude and direction and since it has both magnitude and direction it is therefore considered a vector
What is Vector quantity?
Associates the direction taken with the speedAny quantity that has direction and magnitude associated with it is considered a vector quantity. An example of a vector quantity would be velocity. It must be expressed with reference to a direction.-aerol_

What is the effect of multiplying both sides of an inequality by a negative number?
It changes the direction of the inequality.
What charateristics do all living things have in common?
There are three criteria for something to be described as living/an organism: It must eat It must move of it's own accord It must be able to reproduce
