Unit 7 motion test

Front

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

Back

The formula is d = v x t, where d is distance, v is speed, and t is time.

Front

If a person walks at a speed of 3 km/h, how far will they walk in 30 minutes?

Back

They will walk 1.5 km.

Front

What must be true about the speeds of two jets that are refueling each other in order to avoid a time delay?

Back

The speed must be the same for both jets.

Front

How do you convert minutes to seconds when calculating distance?

Back

Multiply the number of minutes by 60 to convert to seconds.

Front

If a cyclist slows down from 24 mi/hr to 6 mi/hr in 8 seconds, how do you calculate deceleration?

Back

Deceleration is calculated using the formula: (final speed - initial speed) / time.

Front

What is the deceleration of a cyclist who slows down from 24 mi/hr to 6 mi/hr in 8 seconds?

Back

The deceleration is -2.25 mi/hr².

Front

How far will you travel in 3 minutes running at a rate of 6 m/s?

Back

You will travel 1080 meters.

Front

What is the total distance traveled if Bob walks 2 blocks east, 4 blocks south, and 2 blocks west?

Back

Bob traveled a total of 8 blocks.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the starting point to the endpoint.

Front

How do you calculate speed?

Back

Speed is calculated by dividing distance by time: v = d / t.
