Why is speed classified as a scalar quantity and velocity classifed as a vector quantity?
Vectors have speed AND direction. Speed is classified as a scalar quantity because it only has magnitude (numerical value and unit of measurement) such as 50 mi/h. Velocity is classified as a vector quantity because it has magnitude and direction, 50 mi/h north. By including direction, you are giving more information than a scalar quantity (requiring one unit).

How are vectors shown graphically?
↑ ↓ ← → ↖ ↗ ↙ ↘ A vector is a line segment originating in an object, on the line of action. The line of action is an imaginary line, for example, a dropped ball has a line of action passing through its center perpendicular to the ground, and the vector's origin would typically be placed at the top, center, or bottom of the ball. The length of the line segment indicates its relative magnitude and an arrowhead gives it direction. A vector is commonly used to show the size and direction of a force, in newtons (N). 11 N o-----> 50 N <--------------------o ?? N o------------> Take the case of an 11 kg ball falling under the influence of gravity. We could draw a vector pointing up (90 degrees) from the ball, label it as "-108 N", or we could draw a vector pointing down (270 degrees) from the ball, and label it as "108 N". Both are acceptable, and would have the same length, but opposite direction. You could not draw a vector pointing to the right or left. This would indicate the ball is moving horizontally rather than vertically.
What is velocity how is it different from speed?
In common language, the terms are used interchangeably. But in physics, speed is a scalar; velocity is a vector. That is, a speed is just a number (and a unit) - for example, 50 kilometers/hour. But when it is important to distinguish a direction, you talk about a velocity. For example, "50 kilometer/hour to the north". Velocity is a speed AND a direction. "50 km/hour north" and "50 km/hour east" are the same speed but different velocity.
How is the resultant displacement affected when 2 displacement vectors are added in a different order?
Assuming your talking about simple math of vectors, each vector is made up of components in different directions and magnitudes. Vector=V=ui+vj+wk Where i is the unit vector in the x direction, v is in the y direction, and k is in the z direction. u,v,w are the components each of these directions. If North is in the y direction and East is in the x direction, then a person traveling at 50 mi/h in the Northeast direction would have a Velocity in both i and j direction V=ui+vj Where 50mi/h=25*sqrt(25)i+25*sqrt(25)j V=sqrt{[25*sqrt(25)i]^2+[25*sqrt(25)j]^2}=50 All of this said, you simply add the components of the two vectors together, i's plus i's and j's plus j's.
The length of a vector arrow represents its?
The direction of the arrow represents the direction of the force; the length of the arrow is proportional to the magnitude of the force.
What is magnitude in physics?
In physics, quantities can be subdivided into two groups: scalar quantities and vector quantities. A scalar quantity is a quantity with magnitude and a unit. A vector quantity is a quantity with magnitude, a unit, and a direction. Obviously, magnitude is required for both, but what exactly is magnitude?Magnitude is simply the "size" of a quantity. Magnitudes are expressed in numerical form; e.g., 450, 0.45, 2/3, etc.A common example of a scalar quantity is speed. If a man is driving at a speed of 50 km/h, we say the magnitude of the scalar quantity is 50. Notice that the sentence "I am driving 50" is incomplete. Therefore, the magnitude is equipped with a unit, in this case km/h (kilometres per hour).A vector example is velocity, which is simply speed with a direction. If a plane is traveling at 240 m/s [East], then the magnitude of its velocity is 240 m/s, just like what the magnitude of its speed would be. But, since velocity is a vector, you must include the direction as well.
Why is speed classified as a scalar quantity and velocity classifed as a vector quantity?
Vectors have speed AND direction. Speed is classified as a scalar quantity because it only has magnitude (numerical value and unit of measurement) such as 50 mi/h. Velocity is classified as a vector quantity because it has magnitude and direction, 50 mi/h north. By including direction, you are giving more information than a scalar quantity (requiring one unit).
Diffrentiate between vector and scalar quantities?
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
What does 50 j stand for in measurement?
50 Joules, a measure of energy, or a vector of magnitude 50 (usually) upward or towards the North.
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.
What are the major concepts of a scalar and vector quantity in physics?
That vectors are just scalars WITH a direction. (for example 50 miles is a scalar distance, but 50 miles north is a vector)
Which are vectors and which are scalars?
A scalar is a quantity that describes magnitude(size) only. It does not include direction. Examples: Distance (2 cm, 4km) Speed (50 km/h) Mass (3g, 45 kg) A vector is a quantity that describes both magnitude and direction. Examples: Displacement (6km north) Velocity (60 km/h east) Force (15N downward)
What is the direction of resultant vector when a vector of 25 units south is added to a vector 25 units east?
50
What quantities are vectors?
Vector quantities are quantities that have both magnitude and direction. An easily understood example is velocity, which has both speed (the magnitude component) and direction. If we say 60 miles per hour or 8 knots per hour, and we add direction, like east or west, or course 220 magnetic, for example, we're talking about a vector. Electromagnetic fields also have amplitude (a measure of magnitude) like 10 volts/m and direction east or north for example. It really is that simple, and the investigator only has to remember the direction component and add it to a magnitude to lock in the idea.Light is not a vector quantity, it has size and the speed of light 300 mega meters/second, but it does not have a direction. Another example is like saying I was driving home at 60 mph. The '60 mph' is a speed, but not a velocity (a vector) because there is no direction specified.It is important in science to distinguish between vectors and real quantities. Real quantities do not have a direction. This can be seen as no direction or it can be seen as omnidirectional. Omnidirectional would be wrong, at best reals could be said to be origin directional. Positive real could be said to be toward the origin and negative real could be said to be away from the origin. Vectors are related to the origin and directional axis. Real numbers define the origin and a real axis, vector quantities define specifically directions and directional axis based on the real zero point.
Are scalars a measured quantity?
A scalar is anything that has only a magnitude. Usually people contrast scalars with vectors. Speed and temperature are scalars. They only have a magnitude (50 mph or 32 degrees) Velocity and acceleration are vectors. They have both a magnitude and a direction (50 mph north, 9 m/(s^2) downwards )
