a hockey puck slides 36m along the ice straight toward the goal. Suddenly it is hit such that it takes a sharp, instantaneous right turn, and travels 28 meters. How far has the puck traveled? How far is it from wher it started?
The term vector can be used in a variety of ways in science. In epidemiology, the study of disease spread, a vector is an organism that carries the disease from one host to another. So, for example, a mosquito is the vector of the organism that causes malaria. The vector may or may not be affected by the disease causing organism, but the point is that it is a third player in the interaction that includes host, parasite, and vector. Another definition of vector is the representation of a quantity that has magnitude and direction, and can be depicted by an arrow with a certain length (magnitude) and angle (direction). This can be helpful in science when one wants to sum or multiply quantities that have magnitude and direction, and there are rules for doing this that can be found in the field of "vector calculus" or "vector algebra". For example, in the Lotka-Volterra model of predator-prey dynamics, one can deduce outcomes of interactions by using vector algebra, and can determine if the predator and prey can coexist stably or not.

a vector quantity has both direction (sign) and magnitude like displacement towards right or left (direction) and has a certain value (magnitude)
Any physical quantity which has both direction and magnitude is called a vector. A quantity must also obey the 'Triangle law of vector addition' to be called as a vector. For example displacement is a vector, u can say a person moved 5 km (magnitude) along west(direction). But electric current is not a vector, it has magnitude and its direction is from +ve terminal to -ve terminal but it doesn't obey triangle law. Rather currents are added as scalars.
Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity.
To make it easy, vector quantities have a direction aswell as a magnitude.While scalar quantities just have a magnitudeAn example of a scalar quantity is "Speed" and the vector quantity would be "Velocity"
analytical method.
Scalar quantities are an amount, for example 5 pounds, 15 feet, etcetera. Vector quantities are an amount coupled with a direction, for example 20 miles northwest, 7 meters south, etcetera.
Scalar quantities are defined as quantities that have only a mganitude. Vector quantities have magnitude and direction. Some example of this include Scalar Vector Mass Weight length Displacement Speed Velocity Energy Acceleration
Scalar quantities - quantities that only include magnitude Vector quantities - quantities with both magnitude and direction
It is necessary to know the magnitude and the direction of the vector.
Yes, it is a vector quantity.
Not at all. Scalar are numerical quantities without direction (for example time) where as vectors are numerical quantities with direction (for example gravitational force downward)
Vector quantities are those that must be described with both a magnitude and direction. Scalar quantities can be described with only a single value.
Describe scalar and vector quantities. Include a definition and provide at least one example of how they are alike and how they are different.
Mainly because they aren't scalar quantities. A vector in the plane has two components, an x-component and a y-component. If you have the x and y components for each vector, you can add them separately. This is very similar to the addition of scalar quantities; what you can't add directly, of course, is their lengths. Similarly, a vector in space has three components; you can add each of the components separately.
No. Force and acceleration are vector quantities.
