Calculating Speed

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

If an object travels 100 meters in 10 seconds, what is its speed?

Back

10 m/s

Front

What units are commonly used to express speed?

Back

Meters per second (m/s) and kilometers per hour (km/h)

Front

How do you convert speed from m/s to km/h?

Back

Multiply the speed in m/s by 3.6.

Front

What is the average speed of an object?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

If a car travels 150 km in 3 hours, what is its average speed?

Back

50 km/h

Front

What is wave speed and how is it calculated?

Back

Wave speed is calculated using the formula: Wave Speed = Frequency x Wavelength.

Front

If a wave has a frequency of 2 Hz and a wavelength of 5 m, what is its speed?

Back

10 m/s

Front

What is the relationship between frequency, wavelength, and wave speed?

Back

Wave speed is directly proportional to both frequency and wavelength.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.
