A car usually remains stationary, when parked, as the hand-brake has been put on.
A stationary car parked on the side of the road does not have kinetic energy, as kinetic energy is the energy of motion and the car is not moving.
A stationary car parked in a parking lot and a book sitting on a table are examples of objects remaining at rest.
When a moving car hits a parked car, energy is transferred from the moving car to the parked car. The kinetic energy of the moving car is transferred to the parked car, causing it to move. Some energy is also converted into other forms, like sound and heat, during the collision.
The momentum of the moving bumper car decreases because some of its momentum is transferred to the stationary bumper car during the collision. According to the law of conservation of momentum, the total momentum of the system (both cars) remains the same before and after the collision.
When a moving car hits a parked car and causes it to move, the kinetic energy of the moving car is transferred to the parked car. This increase in kinetic energy causes the parked car to start moving. Some of the energy is also dissipated as sound, heat, and deformation of the cars during the collision.
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.
Stationary is an adjective: 'I parked my car on a steep hill and made sure that it was stationary before I walked away.'
A stationary car parked on the side of the road does not have kinetic energy, as kinetic energy is the energy of motion and the car is not moving.

A stationary car parked in a parking lot and a book sitting on a table are examples of objects remaining at rest.
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.
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.
Probably in need of a tune up.
The car that rolled into the parked car is at fault.
