propensity
The magnitude of the balls displacement is 9 meters.
Because if you push a car(toy car) and it starts to slow down then it is because of the friction from the wheels between the track. And if thee car does not slow down then it is because the slope is going diagnal and in the same nonstop speed. DOH

By removing the objects you choose to subtract from the group of objects.
Round objects don't have to roll down hill, they can slide if they have a heavier side, but are more likely to roll due to gravity.
Gravity is the primary force that causes objects to move downhill. Objects are pulled downward towards the center of the Earth by gravity, accelerating them as they move downhill.
Gravity is the natural force that causes rocks to fall or roll downhill. Objects are pulled towards the center of the Earth by gravity, leading to the downward motion of rocks on sloped surfaces.
Things roll downhill because of gravity, which pulls objects toward a larger mass, such as the center of the Earth. As an object gains momentum rolling downhill, the force of gravity helps it maintain its motion and accelerate. Friction also plays a role in ensuring the object stays in contact with the surface as it rolls downhill.
If two round objects roll down a hill, the one with the greater mass will roll faster. If they are dropped they will fall at the same rate.
Gravity
A zorb is a large transparent ball in which someone may roll downhill.
The force pulling the snowball down a grassy hill is gravity, the natural force of attraction between objects with mass. As the snowball gains momentum, it overcomes the friction between the snowball and the grass, allowing it to roll downhill.
If the cart is rolling downhill it will roll faster with mass, but on level ground or uphill it will roll faster without mass.
The force of gravity causes a ball to roll downhill. As the ball is positioned higher up the slope, gravity pulls it downward, causing it to accelerate and gain momentum as it rolls downhill. Friction may also play a role in slowing down the ball's movement.
Wind and rain erosion causes rocks to become dislodged will let it fall or roll to the bottom. Wind and rain erosion do cause rocks to roll to the bottom of a hill but more importantly gravity does. Gravity is the main reason :)
Gravity is the force that pulls materials downhill. This force is responsible for the attraction between objects with mass and causes objects to move towards the center of the Earth when on a slope, resulting in a downward pull.
