Motion and Speed Flashcard

Front

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

Back

T = D/S, where T is time, D is distance, and S is speed.

Front

What is a reference point in motion?

Back

A reference point is a stationary object used to determine the position and motion of another object.

Front

How do you calculate distance using speed and time?

Back

Distance can be calculated using the formula D = S * T, where D is distance, S is speed, and T is time.

Front

If a car travels at an average speed of 60 miles per hour, how far will it travel in 2 hours?

Back

The car will travel 120 miles, calculated as D = S * T = 60 mi/hr * 2 hr.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

How do you convert hours to seconds?

Back

To convert hours to seconds, multiply the number of hours by 3600 (since 1 hour = 3600 seconds).

Front

If a runner completes a 100-meter race in 10 seconds, what is their average speed?

Back

The average speed is 10 m/s, calculated as S = D/T = 100 m / 10 s.

Front

What is the significance of a reference point in describing motion?

Back

A reference point allows observers to determine if an object is in motion by comparing its position to the reference point.

Front

How do you find the time taken for a journey if you know the distance and speed?

Back

Use the formula T = D/S, where T is time, D is distance, and S is speed.

Front

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

Back

Speed is equal to distance divided by time (S = D/T), and can be rearranged to find distance or time.
