Kinetic Energy: it is the energy that an object has because of its movement. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do the job. After the work is done, the energy is transferred to the object and the object will be moving with a new constant speed. The transferred energy is known as kinetic energy, and depends on the mass and speed achieved.

Have you ever thought about turning a soccer ball into a renewable energy source?
American researchers, from Harvard University, created a ball that transforms kinetic energy kicks into electricity. It is an invention that can be used as a source for luminaries, to charge electronic devices, such as cell phones and LED lamps.
The invention was called “Soccket”, a mixture of “soccer” and “socket”.
It is estimated that 15 minutes of kicks can generate energy for an LED lamp for about 3 hours. The ball weighs 28 grams, more than an ordinary ball, and is made of resistant and durable material.
The first versions were taken for families that do not have access to electricity, in South Africa, Mexico and Brazil. It was even tested at the 2010 FIFA World Cup.
The balls were also distributed at schools to assist teachers in teaching about energy
Answer:
