The sum of gravitational potential energy and kinetic

Chemistry
1 answer:
Firlakuza [10]3 years ago
7 0

Answer:

Explanation:

Mechanical energy = Gravitational potential energy + kinetic energy

Time            Gravitational potential energy        kinetic energy         Total ME

0                                    4                                                0                        4

2                                     2                                               2                        4

4                                     0                                               4                        4

6                                     2                                               2                        4

8                                     4                                               0                        4

and so on  .....

We see that total mechanical energy is always 4 which is constant .

So gravitational and kinetic energy changes cyclically but total mechanical energy is constant .

trapecia [35]

Answer:

Sand may be deposited as sediments that become sedimentary rocks after hardening, or lithifying. Extreme burial pressure, rising temperature at depth, and a lot of time, will transform just about any rock to become a metamorphic rock.
