![]() ![]() You can convert units to km/h by multiplying the result by 3.6: 27.8 * 3.6 ≈ 100 km/h.Since the initial velocity was zero, the final velocity is equal to the change of speed.Multiply the acceleration by time to obtain the velocity change: velocity change = 6.95 * 4 = 27.8 m/s.Set initial velocity to zero, you're not moving at the beginning of the race.What will be your velocity after 4 seconds? You want to participate in a race with your brand new car that can change its speed with an acceleration of about 6.95 m/s². Divide the distance by time: velocity = 500 / 180 = 2.77 m/s.Change minutes into seconds (so that the final result would be in meters per second).Provided an object traveled 500 meters in 3 minutes, to calculate the average velocity you should take the following steps: It's time to use the average velocity formula in practice. In other words, velocity is a vector (with the magnitude and direction), and speed is a scalar (with magnitude only). The former is determined on the difference between the final and initial position and the direction of movement, while the latter requires only the distance covered. īefore we explain how to calculate velocity, we'd like to note that there is a slight difference between velocity and speed. In order to calculate how much gas will be used during a particular journey, try our gas calculator. The relationship between distance and time is also needed when estimating the fuel use of your car. Remember you can always easily switch between all of them in our tool! In the metric SI system the units are meters per second m/s and kilometers per hour km/h. 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 +. ![]()
