- 速度(velocity)的复数形式为velocities。 - 速率(speed)第三人称单数形式为speeds,复数形式仍为speeds。 4. 用法不同: - 速度(velocity)强调方向,可以用矢量表示;而速率(speed)只用于描述运动速度,为标量。 5. 示例句: - 矢量(velocity):Acceleration and velocity are both vectors.(加速度和速度都是矢量。)...
Velocity Practice Problem 1. What is the velocity of a boat that travels from Nashville to Huntsville (10 miles) in 15 minutes? Answer Speed = distance ÷ time Speed = 10 miles ÷ 15 minutes Speed = 0.67 mi/min Velocity = 0.67 mi/min South Acceleration Definition Formula Acceleration is a...

* (b) use graphical methods to represent displacement, speed, velocity and acceleration. * (c) find displacement from the area under a velocity-time graph. * (d) use the slope of a displacement-time graph to find the velocity.* (e) use the slope of a velocity-time graph to find the...
第一个，是我们最常的速度的意思，不需要精确计算第二个，一般是计算后的速度，所以数学和物理上常用，或强调一个正常，准确的速度概念时常用最后一个是加速度，当然不同了以上是我自己的总结，我认为就可以区别这三个词了，你还可以多参考其他答案 ...
acceleration是加速度, velocity是速度,speed是位移,知道意思应该就没问题了吧

Let's briefly review what we've learned about the principles and formulas involving speed, velocity, and acceleration in physics. Speed is a measure of distance traveled over a certain amount of time, while velocity measures displacement over time, as opposed to distance. Speed is the same as...
