QuestionWill a

Cricket player’s

strength and age affect the way they play Cricket?Slide3

Background Research

“A fast baller can send the ball at a fantastic speed so it can reach the bat in ½ of a second, this manipulates the mind.” (www.sciencekids.co.nz/videos/sports.html)

“Cricket demands the stamina of an athlete, flexibility of a gymnast, strength of a jumbling thrower, and the mind of a chess master” (www.sciencekids.co.nz/videos/sports.html

)Slide4

Background Researchcontinued…

“The total force on the Cricket ball is zero, so it falls at a constant speed after the first 100m”

(www.physics.usyd.edu.au/~cross/cricket.html)

“The average force on the ball is 8,800 N, enough to lift a mass of 880 kg off the ground”

(www.physics.usyd.edu.au/~cross/cricket.html)

“The fastest Cricket pitch was 100.2 mph or 161.26 km/h, done by Shoaib Akhtar”

Hypothesis

T

he older the person is, the more strength they will have, therefore they will have the ability to pitch farther and faster. Slide6

Variables

Control- distances: I will compare distances the ball was pitched to the distances professional Cricket players pitched.

Independent Variable- pitcher: The only thing I will change will be the people pitching, so the independent variable is the person pitching.

Dependent Variable- time: I will time the amount of time taken for each pitch to reach the batsman.

Constants-

The same Cricket Ball

Same Location

Same stopwatch

Every pitch will be compared to the same point.

The weather will be the same.Slide7

Procedures

I must gather all the materials that are required for my experiment.

Set up the wicket positioning, in which the area where the ball is pitched

.

I will have to measure the distance between each wicket.

I will have people throw/pitch so I can calculate the speed the ball is traveling in.

I will measure the difference of the pitching speed. Slide9

Results

The results I got

were the pitches made were all based on the conditions pitch, for example in other countries like Australia, England, and New Zealand the pitches (the ground where its pitched) are more bouncy and grassy, its more likely for them to perform fast balls. And in other countries in Asia like India, or Sri Lanka its more likely for them to perform spin balls, because

there are less grassy areas, and the pitches aren’t that even either. Therefore it depends on the pitch.

My experiment was done in a grassy area, so we couldn’t perform the spin ball because it would go spinning somewhere else, so we had to perform the fast ball.Slide12

Conclusion

My hypothesis was incorrect because from the information I have gathered, it shows that the age doesn’t matter when it comes to

bowling

. It’s the force

and the kind of pitch you perform. For example I had my cousins do different types of pitches: the spin ball, a fast ball, and a full toss. Each pitch gave a different result. The ages of the players didn’t matter either, because I thought that the older the person

is,

the faster and farther they would

pitch, yet I

thought

wrong, because the different pitches have different ways of being done. In Cricket there are two types of pitchers: fast bowlers, and spin bowlers. Both older and younger pitchers can play good, but it depends on which pitch they’re making. Like an older person might have less strength but and perform the spin ball, which can also do good in a game. And a younger person has more energy so they can perform a fast ball. So

in conclusion to this the time it takes for the ball to reach the wicket depends on the force the pitcher puts in their pitch, and the pitch performed
