Understanding Speed, Distance, and Displacement

If a jogger runs at 3 meters per second, how far will they travel in 20 seconds?

• 90 meters

• 120 meters

• 30 meters

• 60 meters

What is the average speed if you walk 400 meters in 5 minutes?

• 1.3 meters per second

• 3 meters per second

• 4 meters per second

• 2 meters per second

How can the speed of sound help measure distance?

• By measuring the loudness of the sound

• By using a stopwatch to time the sound

• By counting the number of echoes

• By timing how long it takes for sound to travel to a wall and back

What additional information does displacement provide compared to distance?

• Time taken

• Direction

• Speed

• Temperature

Why does velocity change in circular motion even if speed is constant?

• Because the speed increases

• Because the direction changes

• Because the speed decreases

• Because the path is straight
