Flashcard - Speed

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in kilometers per hour (km/h) or miles per hour (mph).

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

If a train travels 540 km in 6 hours, what is its average speed?

Back

90 km/h

Front

What is the formula to find time when distance and speed are known?

Back

Time = Distance / Speed.

Front

How long would it take to travel 200 kilometers at a speed of 55 km/h?

Back

3.6 hours.

Front

What does 'motion' refer to in physics?

Back

Motion refers to the change in position of an object over time.

Front

What is the unit of speed?

Back

The unit of speed is typically kilometers per hour (km/h) or miles per hour (mph).

Front

What is the velocity of a truck that travels 75 miles north in 2.5 hours?

Back

30 mph north.

Front

What is the relationship between distance, speed, and time?

Back

Distance = Speed x Time.
