Here are 10 one-word answer type questions from the topic Units of Time and Speed with their answers and explanations:
Topic: Units of Time and Speed
Units of Time and Speed refer to the standard measurements used to express time and speed. Time is measured in seconds, minutes, hours, etc., while speed is measured as distance divided by time, like m/s, km/h, etc.
1. Question: What is the basic unit of time?
Answer: Second
Explanation: The basic unit of time in the SI system is the second, represented by ‘s’.
2. Question: Which is the larger unit of time used to measure longer durations?
Answer: Hour
Explanation: Hour is used to measure longer durations of time, and 1 hour = 60 minutes.
3. Question: What is the basic unit of speed?
Answer: m/s
Explanation: The basic unit of speed in the SI system is metre per second, written as m/s .
4. Question: Which unit of speed is commonly used to measure speed of vehicles?
Answer: km/h
Explanation: Kilometre per hour (km/h) is commonly used to express the speed of vehicles.
5. Question: What is the symbol for the unit second?
Answer: s
Explanation: The standard symbol for the unit second is ‘s’.
6. Question: Which term is used when we calculate total distance travelled divided by total time taken?
Answer: Average
Explanation: Average speed is obtained by dividing total distance by total time taken.
7. Question: What is the relation between speed, distance, and time?
Answer: Distance/Time
Explanation: Speed is calculated by dividing the distance covered by the time taken.
8. Question: What is the unit of speed used to measure the speed of very slow animals like tortoise?
Answer: cm/s
Explanation: For slow speeds, the unit centimetre per second (cm/s) is used .
9. Question: How many seconds are there in one minute?
Answer: Sixty
Explanation: One minute is equal to 60 seconds.
10. Question: Which device records the speed of a vehicle directly?
Answer: Speedometer
Explanation: Speedometer is an instrument in vehicles that shows the speed in km/h.
