Difference between vector and scalar quantity?
A vector is a quantity with a direction that matters, like force, velocity, acceleration, etc. A scalar is a quantity with no direction, like temperature, cost, mass, etc.
What are the examples for vector quantities?
A vector quantity is any quantity in which a direction is relevant. Some examples include position, velocity, acceleration, force, momentum, rotational momentum (the vector is defined to point in the direction of the axis in this case), torque, etc.
Is force a derived quantity?
Yes, Force is a derived quantity. Force is the first derivative of Energy, F=XE.Force and energy are quaternion quantities consisting of a scalar S and a vector V.The scalar energy is called a potential energy like gravity Es=-mMG/r = -mu/r. The vector energy is Ev=mcV where V is the vector velocity.
Is height a scalar or vector quantity?
WEIGHT is a VECTOR quantity .. because the weight has the direction into the surface of the earth to the down effected by the gravity .. but mass is a scalar quantity like 90 kg .. so .. WEIGHT IS VECTOR ..
Is momentum a scalar quality?
A vector quantity is one which transforms like the coordinates. In other words, if a coordinate system is transformed by an operator , any vector quantity in the old coordinate system can be transformed to its equivalent in the new system by the same operator. An example of a vector quantity is displacement (r). If displacement is a vector, the rate of change of displacement (dr/dt) or the velocity is also a vector. The mass of an object (M) is a scalar quantity. Multiplying a vector by a scalar yields a vector. So momentum, which is the mass multiplied by velocity, is also a vector. Momentum too transforms like the coordinates, much like any other vector. The definition of a vector as a quantity having "magnitude and direction" is simply wrong. For example, electric current has "magnitude and direction", but is a scalar and not a vector.

Is force a scaler or vector quantity?
Force is a vector quantity. When my brother and I were both little guys, I could pull on the toy with a million tons of force toward me, and he could pull on the same toy with a million tons of force toward him, and the toy didn't move, because the vector sum of the external forces acting on it was zero. You could not do that today, as they no longer build toys like they used to.

Is force a vector quantity?
A "vector quantity" is any quantity where the direction matters. In the case of a force, the end result is not the same whether you and I pull an object in the same direction; in opposite directions; or perhaps at a right angle. Briefly, the direction of the force is relevant.
What is the difference between scalars and vectors using displacement and distance?
A scalar is a real quantity like distance and a vector is a vector quantity like displacement.Displacement is the product of a distance and a direction,Displacement =DistancexDirection.
What is difference between Vector and Scalar Quantity?
A scalar quantity is just that, a quantity. Mass, speed, weight, height and the like. A vector quantity has direction. A mass moving South, 30 m/s straight up and all quantities having directionality included.
What two quantities are necessary for a vector quantity?
a vector quantity has both direction (sign) and magnitude like displacement towards right or left (direction) and has a certain value (magnitude)
Can scalar quantities be added together?
Yes, scalar quantities can be added, as long as they are the same dimension and you keep units straight. For example you cannot add cubic meters to square meters. But (especially in the imperial system) pounds and ounces, or feet and inches are added, and displayed in that fashion. Minutes and seconds is another.
Why pressure is scalar quantity where as force is vector quantity?
Pressure is the force acting in all directions on an area while force is a push or pull in a direction. To understand this, we have to know how pressure or force originates. While the force is applicable to rigid materials, the term pressure is applicable for bulk materials (like water) where individual particles are considered as soft. When a force is applied from one direction on the soft particle, the soft particle gets distorted and projects out in all directions. Pressure thus do not have any unique direction but all, while a force has a unique direction. When a bomb blasts, it effects in all directions in air whereas if a running car hits, it effects in the specific direction only. A parameter effecting in all directions uniformly is considered as if it is a scalar. The pressure acts to all the directions uniformly. I mean in 360 degrees. So, we can't define a direction for pressure. The formula P= F/A is only the magnitude relation, not direction. It should be kept in mind. Mathematically, it can be understood as pressure is the ratio of force and vector area (which has direction along the normal to the surface upon which the force is acting, and if the force is not normal to to the surface we take component of force along normal. )
