What else can I help you with?
A quantity that requires both magnitude and direction?
I had this question in my physics class as well and the answer is vector :)
Explain how velocity differs from speed?
Velocity includes not only the speed of an object but also its direction of motion. Speed is scalar quantity, meaning it only considers magnitude, while velocity is a vector quantity that requires both magnitude and direction.
Is mass and acceleration scalar or vector qualities?
Mass is a scalar quantity, as it only requires a magnitude to describe it. Acceleration is a vector quantity, as it involves both magnitude and direction to fully describe it.
What two pieces of information are necessary in order to define a vector quantity?
To define a vector quantity, you need both magnitude (size or length) and direction. For example, in physics, velocity is a vector quantity that requires both the speed (magnitude) and the direction in which an object is moving to be fully described.
What is meant by scalar and vector?
Basically, a scalar magnitude is one in which the direction is not relevant; a vector magnitude is one in which the direction is relevant. A scalar can be represented by a single real number; a vector requires at least two numbers (for example, the x-component and the y-component; or alternately a magnitude and a direction).

Why is speed classified as a scalar quantity and velocity classified as a vector quantity?
Speed is the rate of which an object is moving altogether and is a scalar quantity and thus only requires a magnitude and is found by the use of the formula speed=distance/time SI unit = m.s-1 Velocity is the rate of which a object is moving in a given direction, so is vector quantity and both a magnitude and direction are required found by the formula velocity=displacement/time SI unit = m.s-2

What is the difference between vector and scalar quantities?
Vector quantity is a quantity characterized by magnitude and direction.Whereas,Scalar quantity is a quantity that does not depend on direction.
Why weight is a scalar?
Weight is a scalar because it only has a magnitude (amount) and no specific direction. It is a measure of the force of gravity acting on an object, defined as the mass of the object multiplied by the acceleration due to gravity. Since it only requires a magnitude to describe it, weight is considered a scalar quantity.
Why time is not a vector quantity?
No, time is a scalar quantity. And any interval of time is also scalar. It has magnitude only. A vector quantity is a scalar quantity that has the added or extra "dimension" of direction. Time has magnitude, but is not considered to have direction as such. Time, though it can be "tricky" to deal with in quantum Is_time_a_vector_or_scalar_quantity, is generally thought of as moving "forward" and generally cannot more in another direction. (Save the "exceptions" for more advanced physics, please.)
Is displacement a scalar quantity?
Yes. Displacement requires a direction and hence is a vector
What additional information is needed for velocity that is not needed for speed?
In physics, velocity is the rate of change of position. It is a vector physical quantity; both magnitude and direction are required to define it. The scalar absolute value (magnitude) of velocity is speed. For example, "5 meters per second" is a scalar and not a vector, whereas "5 meters per second east" is a vector. So in short the difference between velocity and speed is that speed is determined by magnitude whereas both magnitude and direction determine velocity.
