Speed is related to distance travelled, whereas velocity is to displacement. The main difference between speed and velocity is that speed gives an idea of how fast the body is moving, whereas velocity not only gives the idea of the body's speed but also tells the direction in which it is moving. Well, although the concepts are a bit similar, these terms are quite different from each other. Most of us often get confused by the terms speed and velocity, as the concepts of both of these terms revolve around how fast something is moving. Here, tv – tu is the time elapsed from u to v. The delta (Δ) in front of the time (t) displays the change in time, which can be written as tv − tu. The final velocity of an object is equal to its initial velocity plus acceleration multiplied by the time it travelled, and can be given as:Īs the equation shows for a given object, you can calculate its final velocity by adding its initial velocity to the acceleration due to force multiplied by the time for which the force applied to it. T = time between the start and end of the acceleration (s) Hence, it can be calculated by using the below formula: The initial velocity (vi) is the velocity of the object before a change due to acceleration. On the other side, the final velocity is the speed (along with direction) of the same moving object once it has reached its final position. Initial velocity is the speed (along with direction) of the object with which it starts moving. Some of the units in which one can express velocity is miles per hour (mph), kilometres per second (km/s), and kilometres per hour (kph). T is the time the object took to complete the movementĪlthough the SI unit for velocity is m/s (meter per second), it can be expressed in any unit of d/t (distance per time). R is the rate (sometimes denoted as v, representing velocity) A simple formula given below is the most common and easiest way to calculate velocity. For instance, if an object travels towards the west at 5 meters per second (m/s), then its velocity will be 5 m/s to the west. Hence, to determine the velocity as per this definition, we should be familiar with both the magnitude and direction. Velocity is a vector measurement of the rate of motion of an object and the direction in which it is moving. Here, we will be going to discuss this concept in detail. Considering such difficulties and thus eliminating them, our scientists came up with the concept of velocity to help the observers in identifying the faster or slower objects with ease. However, determining the faster object is quite difficult if the two are travelling in opposite directions. Identifying which of the two objects is moving faster than the other one is easy if they both are moving in the same direction. Let’s take an example where two objects are moving. It is what tells how slow or fast something is moving. In simple words, the term velocity gives us an idea of the speed at which an object is moving in a particular direction. ![]() To be specific, the velocity of an object can also be defined as the rate of change in the object’s position corresponding to a frame of reference and time. Velocity in physics is defined as a vector measurement of the direction and rate of the motion. ![]()
