Here are 10 one-word answer type questions from the topic Slow or Fast along with their answers and explanations:
Topic: Slow or Fast
In our daily life, we see that some objects move faster while others move slowly. The speed of an object is determined by how much distance it covers in a given time. Faster objects cover more distance in less time compared to slower ones.
1. Question: What is the term used to compare how fast or slow an object is moving?
Answer: Speed
Explanation: Speed is the distance covered by an object in unit time. It helps us to compare which object is moving fast and which one is slow.
2. Question: In a 100-metre race, what decides who is faster?
Answer: Time
Explanation: The one who covers the distance in the shortest time is considered faster.
3. Question: What do we call the motion when an object moves at a constant speed?
Answer: Uniform
Explanation: If an object covers equal distances in equal intervals of time, its motion is called uniform motion.
4. Question: What is the motion called when speed keeps changing?
Answer: Non-uniform
Explanation: When an object does not cover equal distances in equal intervals of time, it is called non-uniform motion.
5. Question: Which is faster – bicycle or bus (as per textbook example)?
Answer: Bus
Explanation: In the example, the bus covers more distance in the same time compared to a bicycle, so it is faster.
6. 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 (m/s).
7. Question: What term is used when two objects cover equal distances in unequal time?
Answer: Speed
Explanation: The object which covers the distance in lesser time has higher speed.
8. Question: Which device in vehicles shows the speed directly?
Answer: Speedometer
Explanation: A speedometer is a device fitted in vehicles to show the speed at which the vehicle is moving.
9. Question: Which device in vehicles records the total distance moved?
Answer: Odometer
Explanation: An odometer measures the total distance covered by a vehicle.
10. Question: What is the motion of vehicles on a straight road an example of?
Answer: Linear
Explanation: The motion of vehicles on a straight road is an example of linear motion.
