About baseball and tennis, what is a baseball like, and how is it different from the shape of a tenn

The basic form of a baseball is a sphere that can be held by the hand. Unlike tennis balls, there are the following differences in color and material.

1. The circumference of a baseball.

It's centimeter to centimeter. The diameter is about 74 mm.

2. The diameter of the tennis ball is between (and cm). i.e. between 65 mm and 69 mm.

Second, the appearance of the two is different.

1. The outer surface of the baseball is made of two pieces of white horseskin or cowhide wrapped with flat threads. The spherical surface is smooth and leathery.

2. The exterior of the tennis ball needs to be made of textile materials.

Uniformly wrapped, the color is white or yellow, it is a textile fabric, and the spherical surface has a rough feeling.

Third, the weight of the two is not the same.

1. The weight of a baseball is gram to gram.

2. The weight of a tennis ball is between and grams.

Fourth, the elasticity of the two is not the same.

1. Baseballs are round cork.

Rubber or similar substances are used as spheres and are wound with twine, so their elasticity is limited.

2. The tennis ball is in free fall from a height of 100 inches (254 cm) to the concrete floor.

, the height of ** should be between 53 inches (cm) and 58 inches (cm). Therefore, it is more elastic than baseball.

1. Baseballs are earthy yellow and also white, baseballs have stitched stripes, and tennis balls are light yellow.

2. Baseballs are made of round cork.

The ball is made of rubber or similar substance, wound with twine, and then wrapped with two pieces of white horsehide or cowhide tightly sewn with flat thread. The spherical surface should be smooth. The weight is gram to gram.

The circumference is centimeters to centimeters (centimeters in diameter). The elasticity is: from the height of the meter freely on the marble slab with a thickness of 6 cm, it can be ** meters to the height of meters.

3. Tennis balls are elastic fluffy rubber balls with a diameter of between centimeters and a ball weight of grams. The ball falls from a height of a meter on flat, hard ground, and the height can reach a meter.

Baseballs are spherical in the same shape as tennis balls.

Among them, the baseball is made of round cork, rubber or similar material as the center of the ball, wound with twine, and then two pieces of white horsehide or cowhide wrapped in flat thread and sewn tightly.

Tennis balls, on the other hand, are elastic fluffy rubber balls that are white or yellow in color and have seamless thread marks at the seams.

In this way, the shape is no different, but it is sewn from two pieces of leather, and the tennis ball is one, in addition to the different materials, different sizes, different elasticity, different weights, different colors, and many other differences, omitted.

The difference between balls A baseball is made of a round ball of cork, rubber or similar substance, wound with twine, and then wrapped in two pieces of white horsehide or cowhide wrapped with flat thread.

This kind of essay can be completely imagined, first sketching a picture of your own setting in your head, and then trying to express it in beautiful words, which is a great test of your language organization and ability to translate into words.

The ball of baseball is the baseball, tennis is the sport of tennis, and the tennis ball is the ball of tennis.

The words tennis, soccer, ping-pong refer to the sport of tennis, soccer and table tennis, and if you want to refer to the ball used in this sport, you should add the ball after it and separate it from the previous word, i.e., tennis ball, soccer ball, ping-pong ball.
