Shortest distance is called displacement . displacement =average velocity / average time . It is a vector quantity both has magnitude and direction.But,distance is a scalar quantity having only magnitude.
In math and physics, displacement and velocity are examples of vectors. The definition of a vector is that it is quantity that has both direction and magnitude. A vector is represented by an arrow that shows the direction of the quantity and a length which is the magnitude.
The magnitude of two displacement vectors, of magnitude x and y, is sqrt(x2 + y2)
No. Cos theta (Cos θ) is a trigonometric function. A vector is any physical quantity which has both magnitude and direction. For example, Displacement. Displacement has a magnitude like 240m or 0 or 13 m, etc. It also depends on the direction. If an object moves along the positive direction of x-axis, then the displacement will have a positive sign and if it moves along the negative direction of x-axis, then displacement will be negative. Thus, it has both direction and magnitude and so is a vector. Cos theta is a trigonometric function, strictly speaking.
The magnitude of displacement is equal to distance traveled when motion is in a straight line.
