'Newton-second' is dimensionally equivalent to 'kilogram-meter/second'.
With more genetic variations, the more adaptations will be developed that will help the population survive the changing environment.
For example, if an environment starts to grow lighter fields, a population will start to develop genetic variation that will help camouflage the animal. Like, make the animal start to have lighter skin to camouflage.
When the object slides across the rough surface some of its potential energy will be lost to friction.
<h3>Conservation of mechanical energy</h3>
The law of conservation of mechanical energy states that the total mechanical energy of an isolated system is always constant.
M.A = P.E + K.E
When the object slides across the rough surface, some of the potential energy of the object will be converted into kinetic energy while the remaining potential energy will be converted into thermal energy due to frictional force of the rough surface.
P.E = K.E + thermal energy
