Is it possible to add a vector quantity?
no because vectors must be equal & opposite. is it possible to add a vector quantity to a scalar quantity. no because they have different dimensions and scalars have no direction. explain all motion is relative.
Is vector quantity always the same as a scalar quantity?
Scalar is the measurement of a unit strictly in magnitude. Vector is a measurement that refers to both the magnitude of the unit and the direction of the movement the unit has taken. In other words, scalar quantity has magnitude, such as size or length, but no particular direction. When it does have a particular direction, it's a vector quantity.
What must a vector quantity include?
Vector Quantity: A physical quantity is said to be a vector quantity when it has both magnitude and direction. The scalar quantities are distance, mass, time, volume, density, speed, temperature, and energy, The vector quantities are weight, velocity, acceleration, and force.
How does vector quantity differ from a scalar?
- Scalar: Tensor of rank 0. (magnitude only – 1 component)
- Vector: Tensor of rank 1. (magnitude and one direction – 3 components)
- Dyad: Tensor of rank 2. (magnitude and two directions – 32 = 9 components)
- Triad: Tensor of rank 3. (magnitude and three directions – 33 = 27 components)

Is work done a scalar or a vector quantity Why?
Work lacks direction and only has magnitude. Force and displacement are combined to form the formula for work. Work is a scalar quantity as a result.
Why work done is a scalar quantity?
Work is defined as a scalar because it depends on the net distance involved, regardless of the direction. If the object winds up where it started, no work is performed because the distance is zero. So work is the transfer of energy from one body to another in which direction is not important.
Is work done a vector quality?
Complete answer: Also, we know that work is a dot product of vectors force and the displacement. Since, the dot product is a scalar quantity. So, work is a scalar quantity, it has only magnitude not direction.
Is work an example of scalar quantity?
Scalar Quantity Examples Other examples of scalar quantities are mass, speed, distance, time, energy, density, volume, temperature, distance, work and so on.
Why work is a scalar quantity Quora?
i.e, Work done is the dot product or the scalar product of the force acting on the body and the displacement of the body in the direction of the force. So, from above it is clear that work done is a scalar product of two vector quantities. That is why work done is a scalar quantity.
Why is the inner product between two vectors that are pointing in opposite directions negative?
Because the force acts in the opposite direction of the displacement. The inner product between two vectors that are pointing in opposite directions is negative.
What happens when you constrain motion to one dimension?
If you constrain motion to one dimension, you restrict vector quantities like velocity and make them scalar-like.
What does the negative sign mean in a scalar?
You would probably answer, "No, the negative sign indicates the direction, which is to the left. The scalar quantity is just 3 m/s without the direction
Is temperature a scalar quantity?
It is like temperature it is scalar quantity but it can either positive or negative.
Is a scalar positive or negative?
A scalar can be both positive and negative. The numbers are scalars, and "2" is positive, "-5" is negative.
Is speed a positive or negative quantity?
Because for example, speed is a scalar quantity and it has no direction.And speed can only be positive.
Is a real number a vector?
Mathematically, the Real (and Complex) numbers are both vectors and scalars.
What is work in science?
The concept of work was created to quantify how much (kinetic) energy is expended when a (supplied) force moves an object (with mass). In some sense, energy is the currency of our universe. So in layman’s terms work measures how much it ‘costs’ to perform actions when we must supply a force to move an object. Clearly it can be useful to know how much something is going to cost before deciding to carry out the task.
What is the product of force and displacement?
In layman’s term, Work is the product of Force and displacement. But if we dig a little deeper, then we will realise that:
What is drawing library?
Drawing library for rendering vector graphics such as lines, curves, and figures onto raster images.
What is the component of the force in the direction of the displacement of the body?
b. Fcosθ be the component of the force in the direction of the displacement of the body. And the body displaced in the direction of Fcosθ, hence work done by the force in the displacing the body through a distance d is given by
What happens when you divide force by distance?
Or, conversely, dividing distance by force suggests that as the force increases the result tends towards zero and you haven’t done much work in this formulation either. So dividing force by distance - and vice versa - is counter intuitive.
Is work done a scaler quantity?
Work done is a scaler quantity.It is the dot product of two vectors force and displacement.
Is a dot product a scalar?
Dot product of any two vector is scalar…
