Penguin Motion and Measurement Concepts

The video tutorial explains how to calculate the average velocity and average speed of a penguin during a chase. The penguin swims left and right, and the tutorial uses these movements to demonstrate the concepts of displacement and distance. The average velocity is calculated using displacement over time, while the average speed is calculated using total distance over time. The tutorial emphasizes rounding answers to two significant digits.

What is the total distance the penguin swims during the game?

• 12 meters

• 21 meters

• 9 meters

• 3 meters

In the given coordinate system, which direction is considered positive?

• Downward

• Leftward

• Rightward

• Upward

How is average velocity calculated?

• Distance divided by time

• Time divided by displacement

• Displacement divided by time

• Speed divided by time

What is the penguin's average velocity rounded to two significant digits?

• 0.38 meters per second

• 0.375 meters per second

• 0.40 meters per second

• 0.35 meters per second

If the penguin swam 15 meters to the left and 10 meters to the right, what would be the displacement?

• 5 meters to the right

• 5 meters to the left

• 0 meters

• 25 meters

What is the elapsed time for the penguin's swim?

• 6 seconds

• 12 seconds

• 8 seconds

• 10 seconds

What is the key difference between average speed and average velocity?

• Average speed considers direction, average velocity does not

• Average velocity considers direction, average speed does not

• Both consider direction

• Neither consider direction

How is average speed calculated?

• Time divided by distance

• Speed divided by time

• Distance divided by time

• Displacement divided by time

What is the penguin's average speed rounded to two significant digits?

• 2.6 meters per second

• 2.625 meters per second

• 2.5 meters per second

• 2.7 meters per second

If the penguin's average speed was 3 meters per second, how far would it swim in 8 seconds?

• 30 meters

• 18 meters

• 21 meters

• 24 meters
