Definition of velocity in English:

velocity

nounPlural velocities vɪˈlɒsɪtivəˈlɑsədi

1The speed of something in a given direction.
速度，速率
the velocities of the emitted particles
发射粒子的速率。
Example sentencesExamples
- A rain droplet's readiness to fall and its fall velocity are not controlled by the density of the droplet, but by its size.
- It dealt only with a specific type of motion: objects moving at a constant velocity.
- However, if we can measure the distance to the Sun we can also calculate the velocity of the Earth relative to the Sun.
- His average velocity on the fastball was ninety miles per hour on the button.
- Wind shear velocities have been measured to 212 knots.
- Maximum wind velocity reaches 20-25 m/s.
- Since a change in either speed OR direction means a change in velocity, the object's velocity is not constant.
- The two bodies will meet at a relative velocity of 10.3 kilometers per second.
- The further away from the center of rotation that the torque is applied the more velocity it causes.
- Similarly, if two objects are moving with the same velocity, one with twice the mass of the other also has twice the momentum.
- Calculating the angular velocity of the Earth is a deceptively easy task.
- Anti-matter has mass and when mass moves at a high velocity, there is an overall increase in energy.
- In 1660, together with Borelli, Viviani measured the velocity of sound by timing the difference between the flash and the sound of a cannon.
- Roller coasters are also good demonstrators of speed, velocity, and acceleration.
- Clearly, much depends on the direction and magnitude of the velocity and of the strength of the gravitational field.
- If an object is moving in one direction without a force acting on it, then it continues to move in that direction with a constant velocity.
- He noticed Venus move, he was able to determine its direction and its velocity and very importantly he was able to determine its angular diameter.
- Accelerometers measure changes in the velocity of the object to which they are attached.
- Hubble discovered that the galaxies are moving away from us with a velocity proportional to their distance.
- In many cases, air resistance will produce a drag force which is proportional to the velocity squared.

  The trouble is that all these measures of money cannot be relied on because the velocity of money changes.
  John Maynard Keynes challenged the theory in the 1930s, saying that increases in money supply lead to a decrease in the velocity of circulation and that real income, the flow of money to the factors of production, increased.
