Units of speed (m/s, km/h)

• What is the definition of distance?

  How far something travels from its starting point
• How are speed, distance, and time related?

  • Longer distance in less time = higher speed
  • Shorter distance in more time = lower speed
• What does time measure in the context of distance and speed?


  How long it takes to cover a distance
• Why is meters per second (m/s) useful?

  It is handy for everyday movements.
• How do m/s and km/h differ in terms of distance measurement?

  • m/s uses smaller units for shorter distances
  • km/h uses larger units for longer distances
• What are the two main units of speed?

  Meters per second (m/s) and kilometers per hour (km/h)
• What does the formula distance = speed × time allow us to do?

  Calculate distance when speed and time are known
• What is the relationship between speed, distance, and time?

  • Speed = distance / time
  • Distance = speed × time
  • Time = distance / speed
• What is the speed of running 500 meters in 100 seconds?

  5 m/s
• What does time signify in the speed formula?

  How long it takes
• What is the first step to calculate speed using distance and time?

  Divide distance by time
• If you run at 4 m/s, how far do you travel in one second?

  4 meters
• Why is it important to calculate speed?

  To understand how fast an object moves
• If a car travels at 70 km/h for 3 hours, what is the distance traveled?

  210 km
• If a car drives 120 km in 2 hours, what is its speed?

  60 km/h
• What does the result of speed represent?

  How fast an object is moving
• What does speed indicate about an object's movement?

  How fast something is moving
• What is the calculation for speed when a car drives 120 km in 2 hours?

  speed = 120 km / 2 hours
• What units can be used to measure speed?

  m/s or km/h
• What is the formula to calculate speed?

  speed = distance / time
• How do you calculate speed from distance and time?

  Divide distance by time taken
• What is the relationship between speed, distance, and time?

  Speed equals distance divided by time
• What is the formula that expresses the relationship between speed, distance, and time?

  speed = distance / time
• If you run 500 meters in 100 seconds, what is your speed?

  5 m/s
• How long does it take to walk 100 meters at 2 m/s?

  50 seconds
• How do you convert 15 m/s to km/h?

  Multiply by 3.6 to get 54 km/h
• How does the calculation of time differ from speed?

  Time is distance divided by speed
• What is the speed of driving 180 km in 3 hours?

  60 km/h
• Why is kilometers per hour (km/h) useful?

  It is useful for longer distances.
• What is the speed if you drive 180 km in 3 hours?

  60 km/h
• How does the formula speed = distance / time help in understanding motion?

  It connects speed, distance, and time mathematically
• If a car travels at 60 km/h, how far does it move in one hour?


  60 kilometers
• What are the formulas for converting between m/s and km/h?

  • From m/s to km/h:
  • speed in km/h = (speed in m/s) × 3.6
  • From km/h to m/s:
  • speed in m/s = (speed in km/h) ÷ 3.6
• What does kilometers per hour (km/h) indicate?

  How many kilometers you go each hour.
• What is the conversion factor for hours to seconds?

  1 hour = 3600 s
• If you travel 240 km in 4 hours, what is your speed?

  60 km/h
• What is the result of converting 15 m/s to km/h?

  15 m/s equals 54 km/h
• What is the conversion factor for kilometers to meters?

  1 km = 1000 m
• What is the reverse calculation of finding time?

  Calculating speed using speed = distance / time
• What does meters per second (m/s) indicate?

  How many meters you travel each second.
