Potential energy transforms to kinetic energy on the way down. An object has kinetic energy when it's moving which turns back into potential energy at the top… [The carriage moves up and down ...

As global electricity demand grows, traditional energy sources are under strain. Oceans, which cover more than 70% of Earth's ...

As the book gets faster it gains more kinetic energy and loses more potential energy. Just before it hits the floor all the gravitational potential energy has been converted to kinetic energy.

A new study has used 30 years of data to find areas with the highest potential for generating energy from ocean currents ...
