Speed Measurement Flashcard

Front

What is needed to determine the speed of a ball rolling down an inclined plane?

Back

A stop clock and a measuring tape

Front

What is the relationship that links speed, distance, and time?

Back

Speed = Distance / Time

Front

What is the formula for calculating average speed?

Back

Average Speed = Distance travelled / Time taken

Front

What does an anomalous result mean in an experiment?

Back

A result that does not follow the trend of the results taken

Front

What should be done if an anomalous result is found?

Back

Discount it when analyzing the data

Front

Why is it called 'average speed' instead of just 'speed'?

Back

Because speed varies at different points of the journey

Front

What is the speed of a ball at the start when you just release it down a ramp?

Back

0 m/s

Front

A car travels a distance of 200 meters in a time of 10 seconds. What is the average speed of the car?

Back

20 m/s

Front

A car, traveling with an average speed of 25 m/s, covers a distance of 225 meters. How long does it take the car to travel this distance?

Back

9 seconds
