Give an example of kinetic energy

A river flowing at a certain speed comprises kinetic energy as water has certain velocity and mass. The kinetic energy of an asteroid falling towards earth is very large. The kinetic energy of the aeroplane is more during the flight due to large mass and speedy velocity.

Explanation:

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
