Answer: Because The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill. Once you start cruising down that first hill, gravity takes over and all the built-up potential energy changes to kinetic energy. Gravity applies a constant downward force on the cars.Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released. Gravitational potential energy is potential energy that results from an object's position in a gravitational field, and is equal to the object's weight multiplied by its height.

hope this helps have a nice day❤️

Viruses are organic structures and they are often termed as "organisms at the end of life". Virus is not considered a living as it does not have a biological machinery to replicate.It is a parasite and it needs a host to replicate.

The virus tries its entry through the wounds, respiratory tracts and by passing through insects.

The complete virus particle is known as virion which consists of a nucleic acid surrounded by a capsid, Virus first attach themselves to a host through their surface.
