WebFor example, if the object weighs 30 kg and has a force of 15 N applied to it, then the acceleration would be 4 m/s. Add the quantity obtained from Step 1 and Step 2 to obtain the final velocity. For example, if your initial velocity was 3 m/s and your object acceleration is 4 m/s, your final velocity is 7 m/s (3 + 4 = 7).

What is velocity? (article) | Khan Academy
https://www.khanacademy.org/science/physics/one-dimensional-motion/displacement-velocity-time/a/what-is-velocity
WebA car’s speedometer, for example, shows the magnitude—but not the direction—of the instantaneous velocity of the car. Police give tickets based on instantaneous velocity, but when calculating how long it will take to get from one place to another on a road trip, you need to use average velocity.

Velocity - Wikipedia
https://en.wikipedia.org/wiki/Velocity
WebThe scalar absolute value ( magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI ( metric system) as metres per second (m/s or m⋅s −1 ). For example, "5 metres per second" is a scalar, whereas "5 …

WebIn the same way, speed can be different than the magnitude of velocity. For example, you drive to a store and return home in half an hour. If your car’s odometer shows the total distance traveled was 6 km, then your average speed was 12 km/h. Your average velocity, however, was zero because your displacement for the round trip is zero.

WebFor example, if you drive to a store and return home in half an hour, and your car’s odometer shows the total distance traveled was 6 km, then your average speed was 12 km/h. Your average velocity, however, was zero, because your displacement for the round trip is zero. (Displacement is change in position and, thus, is zero for a round trip.)
