WebJun 21, 2024 · Scalar Product. Scalar product or dot product of two vectors is an algebraic operation that takes two equal-length sequences of numbers and returns a single number as result. In geometrical terms, scalar products can be found by taking the component of one vector in the direction of the other vector and multiplying it with the magnitude of the ... WebThe answer would be "no" if the force makes a right angle to the displacement vector (or to the direction of motion). In such instances of forces at right angles to the displacement, there is no work being done by that particular force. For instance, a vertical force cannot cause a horizontal force.

WebCorrect option is B) Friction is a vector quantity. Vectors are quantities that are fully described by both magnitude and direction. Friction is also dependent on what type of force, in how much magnitude and in what direction, is applied to any object. Solve any question of Motion in a Plane with:-. Patterns of problems. WebFrom Eq. (3), skin friction τ at the wall is evaluated as (4) τ ≡ n ⋅ 2 μ S ⋅ P = μ ω ∂ B × n, where P ≡ I − nn is the tangential projection operator. Eq. (4) shows that skin friction vector τ must be orthogonal to the vorticity vector ω ∂ B at any given point on a stationary wall, as illustrated in Fig. 1. ipmat is hard

Vector quantity. … WebTranscript. Scalars and vectors are two kinds of quantities that are used in physics and math. Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction. Explore some examples of scalars and vectors, including distance, displacement, speed, and velocity. Created by Sal Khan. WebScientists often make measurements.
