Kinetic Books Homework

So, when the toy is at the top, 7 m, it has potential energy, because it is at rest (its speed is 0)Ep = m*g*h Where m is the mass (8 kg), g is the Earth's gravity (9.81 N/kg) and h is the height (7m). So, plugging in our numbers, we get: Ep = 8 kg * 7 m * 10 N/kg = 560 JWhen the toy falls, its energy is transforming from potential to kinetic.

Please note that sometimes teachers use g = 10, in order to simplify the calculations. So, when the height is 0, all the energy is kinetic.

The local teacher in each community with the most nominations will receive up to $300 worth of school supplies, from new technology (tablet, laptop, TV or projector) to art materials (paper, paint, brushes, etc.) to books or other educational materials.

For the same limited time, Kinetic by Windstream is offering new customers free activation inside retail stores July 15 to Aug. “At the start of the new school year, Windstream is taking stock of the ‘supplies’ we need to learn effectively — great teachers and click-quick Internet speeds for homework,” said Jeff Small, Windstream’s president of consumer markets.

The contest is open to teachers in primary and secondary schools.

Nominations may be made in person at any Kinetic by Windstream store before September.

“We’ve made huge investments in our network core transport and last-mile connections recently, and what is it all for if not to get parents and teachers the fast Internet they need to drive education for our kids.” Each nomination will include the name of the teacher and the school, the name of the nominator and an optional comment section where additional information about the teacher may be provided.

“Come by your local Kinetic by Windstream retail store and write a ‘thank you’ to your favorite teachers.

When potential energy is used it is converted into kinetic energy.

You can think of potential energy as kinetic energy waiting to happen.
