Define the term velocity. what are its various units Is it a scalar or vector quantity?
Velocity is a vector quantity, meaning that it has both a magnitude and a direction. Mass, on the other hand, is a scalar quantity; it has a magnitude only. Velocity is measured in units of distance divided by time; for example, meters per second or miles per hour.
Why can velocity be negative or positive?
Yes, "velocity" is a vector so it not only has magnitude but also direction. By convention, an object moving from left-to-right or upward is moving in a positive direction while an object moving right-to-left or downward is moving in a negative direction. "Speed" is a related term but it is a scalar. As such, it has only magnitude. A speed cannot be negative.
What is vector in physics?
Any element of a vector spaceEuclidean vector, a geometric entity endowed with both length and direction, an element of a Euclidean vector spaceCoordinate vector, in linear algebra, an explicit representation of an element of any abstract vector spaceProbability vector, in statistics, a vector with non-negative entries that add up to oneRow vector or column vector, a one-dimensional matrix often representing the solution of a system of linear equationsTuple, an ordered list of numbers, sometimes used to represent a vectorThe vector part of a quaternion, a term used in 19th century mathematical literature on quaternions.this is by mehansa different user it acually simpler than that vector is something with a value of a direction
What is the relationship between speed velocity and acceleration?
velocity (v) = initial velocity (v0) + acceleration (a) x time (t); that is v = v0 + at. The relation is the same for speed ( a scalar) which is velocity ( a vector) without direction assigned; velocity = speed
The speed and direction of a moving object determines the what of an object?
You might be referring to velocity. It is a vector physical quantity and both speed AND direction are required to define it. One can also consider velocity as the rate at which an object changes position.
What is the difference from speed and velocity?
Velocity has a DIRECTION as well as a MAGNITUDE (that is, velocity is a VECTOR quantity if you've learnt that term yet) The magnitude of velocity is called SPEED (just a POSITIVE number/scalar, not a vector)

What is vector and resultant velocity?
A vector is used to represent direction and magnitude of speed. Velocity is the speed of an object and a specification of its direction of motion. Speed describes only how fast an object is moving, whereas velocity gives both how fast and in what direction the object is moving. Therefore a vector can be used to represent a velocity. The term "resultant velocity" implies a change in velocity which can be determined using vector analysis.
What is another term to the size of a vector?
That is often called the magnitude.
Does velocity depend on direction?
Yes - just like any velocity, average velocity is a vector and has a direction associated with it. Speed, on the other hand is only an intensive property which has no specific direction associated with it. You could consider speed to be the magnitude of the velocity vector.
In mathematics what term is used to refer to the quantity that has been both magnitude and direction?
Vector.
Why can velocity be negative or positive?
Yes, "velocity" is a vector so it not only has magnitude but also direction. By convention, an object moving from left-to-right or upward is moving in a positive direction while an object moving right-to-left or downward is moving in a negative direction. "Speed" is a related term but it is a scalar. As such, it has only magnitude. A speed cannot be negative.

Is the velocity of one car traveling 40 km per hour east the same as a car traveling 40 km per hour south?
No. The speed is the same, the velocity is not. The term "velocity" includes the indication of the direction. Two velocities are the same if they have the same magnitude (e.g., both are 40 km/hour), AND the same direction.No. The speed is the same, the velocity is not.

The difference between speed and velocity?
Speed is a scalar quantity and thus a general term; if a car is traveling at 60 mph that is its speed; Velocity is a vector quantity that has speed and direction associated with it. If a car is traveling at 60 mph due east that is its velocity. The two terms are often used interchangeably.
Is kilometers per hour a velocity?
Yes. Actually, to use the precise physics term, if you don't specify a direction (or the direction is irrelevant) it is a speed; when a direction is specified (i.e., you have a vector), it is a velocity.
