noun
Definition
The speed at which something is moving or happening.
Context Alive
The engineers stared at their screens as the rocket climbed higher. It had already reached an incredible velocity just seconds after launch, faster than anything they had tested before. The whole control room erupted in cheers as the numbers kept climbing.
Meanings
1 meaning 1 The Speed at Which Something Moves or Happens (Noun) Very Common ▼
This meaning is about how fast something is traveling or how quickly something is happening. Imagine standing near a highway and watching cars fly past at high speed. A physicist would measure their velocity — exactly how fast they’re moving and in which direction. This is the rate at which something changes position. You might hear “the bullet left the gun at a velocity of 900 meters per second” or “the velocity of change in the tech industry is astonishing.” Or think about a baseball pitcher throwing a fastball — commentators often talk about the velocity of the pitch to describe how hard it was thrown. The word suggests something powerful and measured. ✏️ In everyday conversation, velocity is just a more impressive-sounding way to say “speed.” In science class, though, it’s more precise — it includes both speed and direction.
Vivid ExampleThe storm moved across the coast with terrifying force. Weather stations recorded wind velocity at over 150 kilometers per hour near the center. Residents who hadn’t evacuated yet knew they were running out of time.
Examples from the Street
“The car hit the wall at high velocity — it’s a miracle anyone survived.”
The car struck the barrier at extreme speed — it’s amazing nobody died
“The project is gaining velocity — we should be finished by March.”
The project is picking up momentum and moving faster — we should complete it by March
“He threw the ball with incredible velocity — the batter didn’t stand a chance.”
He pitched the ball at an amazing speed — the person trying to hit it had no hope
Common Patterns
high/low velocity → fast or slow speed
at great/full velocity → at very high or maximum speed
the velocity of something → how fast something is travelling
with incredible/tremendous velocity → at an impressively fast speed
increase/reduce velocity → speed up or slow down
at a velocity of (number) → travelling at a specific measured speed
gain/build velocity → start moving faster, pick up momentum
lose velocity → slow down or lose momentum
the velocity of change/growth → how fast something is changing or expanding
at this velocity → at this rate of progress or speed
muzzle velocity → the speed of a bullet when it leaves a gun
wind velocity → the speed of the wind
escape velocity → the minimum speed needed to break free from a planet’s gravity
terminal velocity → the maximum speed an object reaches when falling through air
velocity and direction → in physics, velocity includes both speed and direction of travel
