# The Power of Strings

Hard
Does the tension of a tennis racquet's strings affect the speed of the ball? Let's find out! In this experiment, five amateur tennis players will use two racquets with different string tensions to serve the ball. The speed of the ball will be measured with a radar gun.

## Hypothesis

The hypothesis is that the racquet with the lower tension level will make the ball travel faster.

## Method & Materials

You will have five amateur tennis players use two racquets with different string tensions to serve the ball. The speed of the ball will be measured with a radar gun.
You will need five amateur tennis players, one tennis court, two tennis racquets with frames of the same weight and design, one box of tennis balls, and a radar gun.

## Results

The results show that all the five tennis players were able to hit and make the ball travel faster when using the racquet with the 50 lbs string tension. This proves that the hypothesis is true.

## Why do this project?

This science project is interesting because it shows how the tension of a tennis racquet's strings can affect the speed of the ball.

## Also Consider

Consider experimenting with racquets of different weights, or measuring the distance traveled by the ball.
