WebDefinition of Velocity . Velocity is a vector quantity used to describe an object's direction of motion and speed. It is often characterized by two types, average velocity, and instantaneous velocity. Average velocity is a vector quantity that relies on the final and initial position of an object. WebFeb 15, 2024 · Velocity of an object is responsible to indicate its position as well as how its position varies with time. It is often defined as the distance covered by an object in a unit time. Velocity can be simply by the formula: r = d/t Where, r = rate (often also denoted as v, symbolising velocity) d = distance the object moved t = time the object took

WebSep 12, 2024 · To get our first two equations, we start with the definition of average velocity: (3.5.5) v ¯ = Δ x Δ t. Substituting the simplified notation for Δ x and Δ t yields (3.5.6) v ¯ = x − x 0 t. Solving for x gives us (3.5.7) x = x 0 + v ¯ t, where the average velocity is (3.5.8) v ¯ = v 0 + v 2. WebSep 12, 2024 · Displacement Δ x is the change in position of an object: (3.2.1) Δ x = x f − x 0, where Δ x is displacement, x f is the final position, and x 0 is the initial position. We use the uppercase Greek letter delta ( Δ) to mean “change in” whatever quantity follows it; thus, Δ x means change in position (final position less initial position).
