Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, measured in meters per second (m/s). It only has magnitude and no direction.

Front

What is the definition of velocity?

Back

Velocity is the displacement per unit of time, measured in meters per second (m/s). It has both magnitude and direction.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is the formula for calculating displacement?

Back

Displacement = Final position - Initial position.

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 initial to the final position.

Front

If an object travels 100 meters north and then 100 meters south, what is its displacement?

Back

The displacement is 0 meters, as the object returns to its starting point.

Front

What is the resultant velocity of an airplane traveling north at 220 m/s with a crosswind of 50 m/s from west to east?

Back

The resultant velocity can be calculated using the Pythagorean theorem: √(220² + 50²) = 226 m/s.

Front

What is the average speed of a car that travels 100 meters in 5 seconds?

Back

Average speed = Total distance / Total time = 100 m / 5 s = 20 m/s.

Front

What is the minimum and maximum resultant displacement of two vectors of 12 m and 16 m?

Back

Minimum displacement = |12 m - 16 m| = 4 m; Maximum displacement = 12 m + 16 m = 28 m.

Front

How do you find the average speed of an object that travels 6.00 meters north in 2.00 seconds and then 3.00 meters east in 1.00 second?

Back

Total distance = 6.00 m + 3.00 m = 9.00 m; Total time = 2.00 s + 1.00 s = 3.00 s; Average speed = 9.00 m / 3.00 s = 3.00 m/s.
