Bouncing Balls: Basketball

Have you asked how much energy can dribble bring? Energy can only mean one thing: the strength of physical or mental activity like basketball. Whenever someone bounces basketball on the floor, it must pass energy to return the ball to the air or to your hands. Without the power of energy, you can not handle the ball in the way you play. Why does not the ball bounce if stopping dribbling?

Xtra: When the ball bounces, basketball converts it to other shapes and loses its kinetic energy. But how many times can basketball bounce before losing all kinetic energy and stopping bouncing back? How do you change if you change some factors, such as the type of surface bounce and the droplet height? Please plan your experiment to see how many times basketball can bounce and how various factors affect this figure, please try it. One factor that affects the collision between basketball and the ground is the type of surface the ball hits. When basketball bounces off the surface, some of its energy is absorbed on the surface. Some surfaces absorb more energy than others. Hard surfaces (such as concrete) will absorb less energy than soft surfaces such as carpeted floors.

Everyone played a rebound ball, but few people actually understand the physical characteristics behind the bounce ball. As you move the sphere over the sphere, the sphere has potential energy. Potential energy is the energy of position and depends on the mass of the ball and the height from the surface. The equation of gravitational potential energy is PE = mgh. Where m is the mass of the ball (kg), g is the gravitational acceleration constant 9.8 m / sec 2, h is the height of the ball (m). When the ball falls into the air, the potential energy becomes kinetic energy. Kinetic energy is the energy of exercise. Kinetic energy formula is KE = 1/2 mv 2. Where m is the mass in kg units and v is the speed in m / sec 2 units. Both potential energy and kinetic energy have Joule (J) units

When basketball bounces, it has two different types of energy: kinetic energy and possibilities. Kinetic energy is the energy generated from an object by the movement of an object. Positional energy is the energy stored in the object - possibility of movement - eg the height from the ground. For example, when playing basketball on the waist it has some potential energy. When you drop a basketball, the ball is pulled down by gravity, and when the ball falls, its position energy turns into kinetic energy. When the basketball hits the coat floor, part of the kinetic energy is converted to sound or heat, part of which change the shape of the ball in a short time (slightly flatten the ball) It is absorbed.
