Vectors are quantities that have a size and a direction.

Examples: Displacement, velocity, acceleration, momentum, force.

Scalars are quantities that have a size but no direction.

Examples: Temperature, cost, speed, length, height, width, age, energy.

=====

Scalar quantities have only magnitude. Vector quantities have both magnitude and direction. Temperature and volume are scalar because they don't have a particular direction.

Velocity and Force (because acceleration actually has a direction) are vector quantities.

Velocity is the combination of the scalar quantity of speed with a direction for that speed. Speed is always a positive number but velocity can be negative and positive because it has a direction.

A vector differs from a scalar in that the vector has a direction in a dimensional sense. Mathematically, the square of a vector is negative and the square of a scalar is positive.

Unfortunately Vectors used in physics are mathematically defective in that the square of J. Willard Gibbs Vectors is positive and nonassociative as a result. Willaim Rowana Hamilton invented vectors and his rule is i^2=j^2=k^2=ijk=1. Tghis is the porper distinction of vectors.

it has direction

Vector quantities have direction as well as magnitude

Vector:

-displacement (10 m North)

-velocity (100 mph south)

Scalar

-distance (10 m)

-speed (100 mph)

Scalars represent a single measure, such as the speed of something. All cars going 30 miles an hour have a speed of 30 miles per hour, no matter in which direction they travel.

Vectors combine magnitude (how large) with a second data item such as directionality. Thus, a car traveling due north at 30 miles per hour has a velocity (note the change of speed, a scalar, to velocity, a vector) of 30 miles per hour north. Another car might have a velocity of 30 miles per hour 10 degrees clockwise of north.

A scalar is one dimensional. It is charted along a single axis. Vectors have two or more dimensions and are charted multidimensional.

Scalars are quantities that only have a length, not a direction. A vector is something that has a length and a direction. A vector is commonly used in maths and it comes in the form of an arrow which has both a direction and a distance. An example of a scalar would be time as time flows forwards at different rates across the universe but across all of these rates you will never find that time has a direction. You can't say I'll be there in 5 minutes in 20 meters.

=======================================================

Scalar has only magnitude. Examples: Time, distance, speed, mass, work, power, energy, frequency, moment of inertia, electric charge, electric current etc.

Vector has both magnitude and direction. Examples: displacement, velocity, momentum, acceleration, force, magnetic field induction, electric field intensity. Even area has to be considered as vector. The beauty is length is a scalar and electric current is also a scalar. But combination of these two would be considered as vector. The current direction would be handed over to the length and thereby " i dl" would be considered as vector.

A vector contains both magnitude and direction, a scalar only contains magnitude.

Scalar quantities have only magnitude (numerical value) such as length.

Vectors on the other hand, have magnitude AND direction, such as acceleration.

What are scalar and vector forces?

There is no such thing as scalar and vector forces. However, there are scalar and vector QUANTITIES, and force is a vector quantity, as all forces have direction and magnitude. Scalar quantities, on the other hand, have only magnitude and no direction.


Similarities between scalar and vector quantities?

Scalar quantities - quantities that only include magnitude Vector quantities - quantities with both magnitude and direction


What are the different derived quantities?

Scalar and vector quantities. Scalar quantities only have magnitude, like the volume of an object. Vectors have both magnitude and direction, like the velocity of an object.


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 are the quantities that identifies scalar and vector quantities?

A vector is characterized by having not only a magnitude, but a direction. If a direction is not relevant, the quantity is called a scalar.


Is work and energy scalar or vector quantities explain?

It is scalar. This simply means that - unlike vector quantities - energy is not defined in a particular direction.


Are force and acceleration scalar quantities?

No. Force and acceleration are vector quantities.


What is vector acceleration?

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"


How are scalar and vector quantities similar?

Scalar and vector quantities give magnitude, and that makes them similar. The difference is that the vector quantity gives direction as well as magnitude. plz check out this for further details vHMnGsOrU5A


What is scaler quantities and vector quantities?

scalar quantity has only magnitude whereas vector quantity has magnitude as well as direction


What is the quantities that has magnitude?

scalar quantities have magnitude only while vector quantities have both magnitude and direction. e.g.s of scalar quantities- distance, mass, temperature, speed e.g.s of vector quantities-displacement, velocity, acceleration, weight, force


Why vector quantities cannot be added and subtracted like scalar quantities?

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.
