Calculating Speed: Who's Faster, Usain Bolt or an F1 Car?

The video tutorial explores the concept of speed, comparing Usain Bolt's speed to that of a Formula 1 car. It explains how to calculate speed using the formula: speed equals distance divided by time. The tutorial demonstrates the calculation of Usain Bolt's speed during his 100-meter world record sprint and compares it to a Formula 1 car's speed. It highlights the importance of using consistent units for accurate comparison and introduces the formula triangle for calculating speed, distance, and time. The video concludes with practice questions to reinforce the concepts learned.

What is speed a measure of?

• The height of an object

• The weight of an object

• The distance an object travels in a certain time

Why can't we directly compare the speeds of Usain Bolt and a Formula One car?

• Because they run on different tracks

• Because they have different units of speed

• Because one is a human and the other is a car

• Because they have different distances

• Divide by 1000

• Divide by 100

• Multiply by 1000

• Multiply by 100

What is the speed of the Formula One car in meters per second after conversion?

• 100.2 meters per second

• 120.2 meters per second

• 104.2 meters per second

• 110.2 meters per second
