What are the physical properties of a ball?

The list should include the following: size, color, weight, bounce height, texture, and sinking or floating in water.

What is ball physics?

The ball slows down, deforms temporarily and shoots back up. The air in the ball acts like a spring—it gets compressed and expands again. During the collision, some of the ball’s energy is converted into heat. As a consequence, the ball shoots up with less energy than it had when it reached Earth.

What is the property of super balls?

Superballs are made of the material vulcanized polybutadiene. When Norman Stingley synthesized this compound in 1965, he gave it the flashy name Zectron. It’s the properties of this compound that make superballs super fun. Polybutadiene molecules are essentially long chains of thousands of carbon atoms.

What are some other properties you might use to describe the sports balls?

Mass • Volume • Density • Texture/Feel • Smell/Odor • DO NOT TASTE the sports balls! CHALLENGE: DO NOT USE COLOR as a property!

What are the physical properties of a soccer ball?

Soccer balls and experimental compressive test An official ball must have a mass of 0.396 ± 0.045 kg, a circumference of 0.685 ± 0.071 m, and an internal pressure of 60.6 ± 11.1 kPa [17]. The outer diameter of the football and futsal balls was 18.10 ± 0.04 and 17.30 ± 0.03 cm, respectively.

What are three physical properties of a tennis ball?

  • Mass: 56-59.4 gm.
  • Size: 2.575-2.700 inches (6.541-6.858 cm)
  • Bounce: 53-58 inches (135-147 cm)
  • Forward deformation: 0.220-0.290 inches (0.559-0.737 cm)
  • Return deformation: 0.315-0.425 inches (0.800-1.080 cm)

What force makes balls bounce?

There is an equal and opposite force on the ball in the upward direction (Newton’s Third Law), which makes it bounce. The conversion of elastic energy to kinetic makes it rise against the ground. In other words, it bounces back into the air!

Why do balls bounce physics?

Its velocity and acceleration vectors are pointing the same direction, meaning upward movement. The ball is less deformed than the maximum deformation stage, and due to its elasticity, it is now pushing against the surface with a force greater than its own weight. This is what will cause the ball to bounce upward.

What are the forces that act on the ball?

The forces are the weight, drag, and lift. Lift and drag are actually two components of a single aerodynamic force acting on the ball.

What is a Super Ball made of?

The Super Ball was invented and patented in 1964 by chemist Norman Stingley. The ball is made of a synthetic material he called Zectron, using a polymer polybutadiene and other materials, a form of artificial rubber.

Why do crazy balls bounce?

When thrown against a hard surface, bouncy balls retain their momentum and much of their kinetic energy (or, if dropped, convert much of their potential energy to kinetic energy). They can thus rebound with an appreciable fraction of their original force.

How high can a ball bounce?

The maximum height it reaches after its first bounce is 70 percent of 200 feet, or 140 feet. After the second bounce, it reaches a height of 70 percent of 140 feet, or 98 feet. In similar fashion, the ball continues to rebound to a height that is 70 percent of the highest point of the previous bounce.

Why is a ball called a ball?

The word ball derives from the Latin word ballare, meaning ‘to dance’, and bal was used to describe a formal dancing party in French in the 12th century. The ballo was an Italian Renaissance word for a type of elaborate court dance, and developed into one for the event at which it was performed.

What was the first ball made of?

The oldest known ball in the world is a toy made of linen rags and string that was found in an Egyptian child’s tomb dating to about 2500 B.C. In highland Mesoamerica, evidence shows that ball games were played starting at least as far back as 1650 B.C., based on the finding of a monumental ball court, though the …

What is ball?

2 usually vulgar : to have sexual intercourse with. intransitive verb. 1 : to form or gather into a ball. 2 usually vulgar : to engage in sexual intercourse.

What are the physical properties of a football?

Today’s football is made of a natural rubber bladder with it being enclosed pebble-grained leather or cowhide or the more high tech ones are made of a rubber material. The ball is filled with air.

What are the properties of football?

Most modern Association footballs are stitched from 32 panels of waterproofed leather or plastic: 12 regular pentagons and 20 regular hexagons. The 32-panel configuration is the spherical polyhedron corresponding to the truncated icosahedron; it is spherical because the faces bulge from the pressure of the air inside.

How is a ball made?

How would you describe a tennis ball?

description. A tennis ball consists of a pressurized rubber core covered with high-quality cloth, usually wool mixed with up to 35 percent nylon. Balls gradually go soft with use, and in tournament play they are changed at regular intervals agreed upon by officials and depending upon such…

Where are tennis balls made?

Some of the rubber comes from Thailand, and the rest from Malaysia and Vietnam. Huge machines mix the material with additives to stabilize it, then knead it and cut it into individual “slugs.” Workers pressure-heat the slugs in giant molds to create hemispheres that look a lot like chocolate.

Why is the tennis ball yellow?

So the International Tennis Federation (ITF) undertook a study that found that yellow tennis balls were easier for home viewers to see on their screens. An official 1972 ITF rule change required that all regulation balls have a uniform surface and be white or yellow in color.

Does ball have motion?

The motion of a ball is generally described by projectile motion (which can be affected by gravity, drag, the Magnus effect, and buoyancy), while its impact is usually characterized through the coefficient of restitution (which can be affected by the nature of the ball, the nature of the impacting surface, the impact …

What type of motion is a bouncing ball?

periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave.

How do you make a physics ball?

Is bouncing a ball an example of Newton’s 3rd law?

Bouncy balls are a great example of Newton’s third law of motion. Kids get these toys all the time and loose them but don’t know that every time they bounce it, there is action-reaction forces. The reaction force is when the ball bounces up from the ground or bounces back from the object it was thrown at.
