British imperial units are feet per second ft/s and miles per hour mph. What is your average velocity? With the velocity calculator, you can find that it will be about 59 mph.įrom the above equations, you can also imagine what are velocity units. For example, you drive a car with a speed of 25 mph for 1 h in the city and then reach 70 mph for 3 h on the highway. You should use the average velocity formula if you can divide your route into few segments.
Average velocity formula - weighted average of velocities:Īverage velocity = velocity₁ * time₁ + velocity₂ * time₂ +.Velocity after a certain time of acceleration:įinal velocity = initial velocity + acceleration * time.In the previous section, we have introduced the basic velocity equation, but as you probably have already realized, there are more equations in the velocity calculator. For example, if you drive a car for a distance of 70 miles in one hour, your average velocity equals 70 mph. The average velocity formula describes the relationship between the length of your route and the time it takes to travel. When an object has only angular velocity, it doesn't displace (the distance is zero), and you can't use the average velocity formula. To learn more about it, head to the speed vs velocity section.Īside from the linear velocity, to which we devoted this calculator, there are also other types of velocity, such as rotational or angular velocity with corresponding physical quantities: rotational kinetic energy, angular acceleration or mass moment of inertia.
You have probably noticed that we use words speed and velocity interchangeably, but you can't do it every time.
Keep in mind that this velocity formula only works when an object has a constant speed in a constant direction or if you want to find average velocity over a certain distance (as opposed to the instantaneous velocity). If you want to put this rule down in the form of a mathematical formula, the velocity equation will be as follows: It is one of the fundamental concepts in classical mechanics that considers the motion of bodies. Velocity definition states that it is the rate of change of the object's position as a function of time.
