Understanding Speed and Distance

Click on the flashcard to see the answer



What is speed?

Speed is the distance traveled per unit of time.

How is speed calculated?

Speed is calculated by dividing distance by time (speed = distance/time).

What units are commonly used to measure speed?

Common units for speed include meters per second (m/s) and kilometers per hour (km/h).

What does it mean if a car travels at a constant speed?

It means the car travels the same distance every unit of time.

How can the speed of an object be increased?

Speed can be increased by increasing the distance traveled in the same time or traveling the same distance in less time.

What is the term for speed that does not change?

Constant speed.

How does average speed differ from instantaneous speed?

Average speed is the total distance divided by total time. Instantaneous speed is the speed at a specific point in time.

What is the formula for distance if speed and time are known?

Distance = Speed × Time.

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

The speed is 50 km/h.

What does a speed of zero mean?

It means the object is not moving; it is stationary.

Can speed be negative?

No, speed is always a positive value.

What happens to speed if distance doubles and time stays the same?

The speed will double.

If a train travels at 60 km/h for 2.5 hours, how far does it travel?

It travels 150 km.

What is the difference between speed and distance?

Speed is how fast an object moves; distance is how far it moves.

How can you tell an object is speeding up?

The object travels more distance in the same amount of time.

Select the correct option


1. What does it mean if a car travels at a constant speed?

The car travels a decreasing distance every unit of time.

The car is not moving at all.

It means the car travels the same distance every unit of time.

The car travels at increasing distances over time.

2. What happens to speed if distance doubles and time stays the same?

The speed will double.

Speed increases by one half.

Speed remains unchanged.

The speed will be halved.

3. What units are commonly used to measure speed?

Inches per minute (in/min) and feet per hour (ft/h).

Meters per minute (m/min) and miles per year (mi/yr).

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

Kilometers per second (km/s) and inches per second (in/s).

4. What is the formula for distance if speed and time are known?

Distance = Time × Distance.

Distance = Speed / Time.

Distance = Speed × Time.

Distance = Speed × Distance.

5. How can you tell an object is speeding up?

The object travels more distance in the same amount of time.

By its decreasing acceleration.

By its constant speed reading.

The object maintains the same speed over a period.

6. How is speed calculated?

Speed is calculated by dividing time by distance.

Speed is calculated by dividing distance by time (speed = distance/time).

Speed equals time multiplied by distance.

Speed is the inverse of velocity.

7. How does average speed differ from instantaneous speed?

Average speed is not as precise as instantaneous speed.

Average speed is always higher than instantaneous speed.

Average speed does not rely on total distance.

Average speed is the total distance divided by total time. Instantaneous speed is the speed at a specific point in time.

8. If a train travels at 60 km/h for 2.5 hours, how far does it travel?

It travels 100 km.

It travels 150 km.

It travels 140 km.

It travels 130 km.

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

The speed is 50 km/h.

The speed is 45 km/h.

The speed is 55 km/h.

The speed is 60 km/h.

10. What is speed?

Speed is the time it takes to travel a distance.

Speed is the distance traveled per unit of time.

Speed is the amount of fuel consumed at given time intervals.

Speed is determined by the acceleration of an object.
