Velocity Unit: Is 30 m/s^2 an Example?

In summary, velocity is a measurement of distance traveled per unit of time and its units are typically expressed as meters per second (m/s) or miles per hour (mi/hr). This can also be used to calculate acceleration, which is the change in velocity per unit of time and is expressed in units of meters per second squared (m/s^2). It is not possible to calculate velocity without a change in time.

For velocity unit, is it, for example, 30 m/s^2?

meters per second, m/s

m/s^2 is acceleration.

Assuming that you are measuring distance in meters and time in seconds, then, since velocity is "distance/time", its units would be m/s.
Acceleration, which is "velocity/ time" would be (m/s)/s= m/s2.

Of course, if you measure distance in miles and time in hours, then velocity would be "miles divide by hours", mi/hr or "miles per hour".

Eh? What does that have to do with this thread?

1. Don't "hijack" some else's thread to ask a separate question. Start your own.

2. You can't "calculate velocity WITHOUT time". You can, under certain conditions, calculate velocity "at a given instant", without a change in time. That's one of the basic questions calculus was developed to answer.
 

Related to Velocity Unit: Is 30 m/s^2 an Example?

1. What is the meaning of "30 m/s^2"?

"30 m/s^2" is a representation of velocity, which is the rate of change of an object's position over time. Specifically, it indicates that the object is moving at a speed of 30 meters per second in a given direction, and that its velocity is changing by 30 meters per second every second.

2. Is 30 m/s^2 a common velocity unit?

No, 30 m/s^2 is not a common velocity unit. Velocity is typically measured in meters per second (m/s) or kilometers per hour (km/h). The unit "m/s^2" is typically used to measure acceleration, not velocity.

3. Can you provide an example of an object moving at 30 m/s^2?

Yes, an example of an object moving at 30 m/s^2 would be a car accelerating from 0 to 30 m/s in 1 second. This means that the car's velocity is increasing by 30 m/s every second, resulting in a final velocity of 30 m/s after 1 second.

4. How does 30 m/s^2 compare to other velocity units?

30 m/s^2 is a relatively high velocity. For comparison, the average speed of a human walking is about 1.4 m/s, while the speed of sound is approximately 343 m/s. This means that an object moving at 30 m/s^2 would be traveling much faster than a person walking, but still significantly slower than the speed of sound.

5. Can velocity units be converted to other units of measurement?

Yes, velocity units can be converted to other units of measurement. For example, 30 m/s^2 can be converted to 108 km/h by multiplying it by 3.6 (since 1 km/h is equal to 1/3.6 m/s). However, it is important to note that the unit "m/s^2" represents acceleration, not velocity, so converting it to a velocity unit may not always be appropriate.
