A car usually remains stationary, when parked, as the hand-brake has been put on.
In terms of physics, it will remain stationary if any frictional force is larger than any force that tends to move it (such as when the car is parked on a slight slope).
It is due to inertia, as observed by Newton in his third law.
It stays the same

Because the frictional force must be greater than forces that would cause the object to move. Example: a car parked on a slope does not move despite the force of gravity acting to pull it down the hill. Why? Because the frictional forces are greater than the forces of gravity.
The potential energy will double too.
Motion is always relative to something. There's no such thing as really "stationary."Stationary only means that the motion of the observed object matches the observer's motion. Example: Reading the book that lies 'stationary' in your lap while you're in a car or on a passenger jet.
Friction of the tires on the road surface ( I think so)
The handbrake is used to stop a stationary car rolling downhill. The transmission can also stop a car from moving when parked.
The hand brake is on.
The car in motion is ALWAYS at fault when it hits a stationary vehicle.
The word "stationary" is an adjective. It describes something that is not moving or fixed in one place.

I hope you got a police report. In any case, whether or not you were parked legally is not relevant. A driver is responsible for damages caused when hitting any stationary object... like a parked car. Just offer to take her to small claims court, or contact a lawyer. Most lawyers would just consider that one fun.
As long as the parked vehicle is parked properly and not illegally parked in any manner, then the vehicle that rear-ended the parked car is at fault. Now if the parked car is sitting illegally (such as double parked or parked in a no parking zone, etc.) then the parked car is at fault or even both the parked car AND the car that hits it are BOTH at fault.
Probably in need of a tune up.
Yup, you guessed it! You You are responsible for "a moving violation" because you were moving and the 'parked car' was stationary. Irregardless of the day, time of day, the moon cycles, astrological signs, sun spots, acts of deity's, the paranormal, fate, karma, etc...
The car that rolled into the parked car is at fault.
It would be the car who had parked illegally because he was not parked in a legal spot.
