What has a physical quantity but no direction?

What has a physical quantity but no direction?

A scalar is a physical quantity that has magnitude but no direction.

Which quantity has only magnitude but no direction?

A quantity which has only magnitude but no direction is known as a scalar quantity.

Is any quantity with both magnitude and direction?

Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity’s magnitude. Although a vector has magnitude and direction, it does not have position.

Can a scalar quantity be negative or zero?

Scalars can be negative, and so can a change in a scalar value. Take temperature: You can have a temperature of -10 degrees.

Is work a scalar or a vector?

Work has only a magnitude but no direction. The formula for work is written as a dot product of force and displacement. Therefore, work is a scalar quantity.

How do you find a position vector with 3 points?

1. UV = (3,1).
2. VU = (-3,-1).
3. The position vector of the point m can be given OM = (-9, -2)
4. R = 3i + 2j + 5k is the position vector, and its length is |R| = √38.
5. The position vector is AB = (1,1), and its length is |AB| = √2.
6. The position vector is OB = (-2,6), and its length is |OB| = √40.

How do you find a position vector at a point?

To find the position vector, subtract the initial point vector P from the terminal point vector Q . Multiply j j by 1 1 .

How do you find the direction of a position vector?

We find its magnitude using the Pythagorean Theorem or the distance formula, and we find its direction using the inverse tangent function. Given a position vector →v=⟨a,b⟩,the magnitude is found by |v|=√a2+b2. The direction is equal to the angle formed with the x-axis, or with the y-axis, depending on the application.
