The Science Behind Measuring Speed
Key Concepts:
Speed is a measure of how fast an object is moving. It's calculated using the formula:
Speed = Distance / Time
In this experiment:
- Distance: The length between start and finish lines (2 meters)
- Time: Measured with a stopwatch as the car moves between lines
- Speed: Calculated by dividing distance by time taken
Real-world Applications:
This same principle is used to measure:
- Vehicle speeds using radar guns
- Athletes' performance in sports
- Velocity of objects in physics experiments
- Industrial conveyor belt speeds
