When running downhill, the main forces acting on a person are gravity, which propels the person downward, and air resistance, which opposes the person's forward motion. The person's muscles contract to control their speed and maintain balance.
The car driving down a hill will have the greatest kinetic energy due to its larger mass and likely higher velocity compared to the 1 lb ball rolling and the 200 lb person running down the hill. Kinetic energy is calculated as 0.5 * mass * velocity^2, so a higher mass and velocity will result in greater kinetic energy.
A force hit the rock which made it roll down the hill.
When a ball rolls down a hill, several forces are acting on it. The force of gravity pulling the ball downward is greater than the force of friction pushing against it, causing the ball to accelerate. This imbalance between the forces of gravity and friction is why the ball rolls down the hill.
When a ball is placed at the top of a hill and accelerates towards the bottom, it experiences both gravitational force pulling it down the hill and the force of friction acting against its motion. These forces combined determine the ball's speed and how far it will travel down the hill.
The main forces that can change a rugged mountain into a low hill are erosion and weathering. Erosion, including processes like water and wind erosion, breaks down the rocks and soil on the mountain, gradually wearing it down over time. Weathering, which involves the breakdown of rocks and minerals on the mountain's surface, also contributes to the transformation of a mountain into a hill.

because the heavier person has more initeria and therefore the forces that would slow the slider down i.e friction, wind resistance, whatever, have less effect on a heavier person that a lighter person
The gerund is "running"

A flood. This is for the blue avatars from Pandora.
It is inertia that keeps you going.

Running Up that Hill was created in 2003.
sand bags!! dig a ditch away from your house
Eat! They need lots of energy, no? :)
It depends on what you mean by slowing down....and how steep the hill is. It's a 5400 lb vehicle running with a 4.6 or 5.4 liter engine.
