The laws of physics.
Because the force is can move objects in any other way :p
When the wind blows it causes energy to move around and makes objects move.
The laws of physics.
When objects in the way of waves move, the waves can be blocked or absorbed by the objects. This can cause the waves to change direction, scatter, or reflect off the moving objects. The movement of the objects can also affect the amplitude and wavelength of the waves.
The orbit
The laws of physics.
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.
Objects move in circles on one giant sphere, with Earth at the center.He had a incorrect observation. Objects move in elliptical orbits on one giant sphere, with the sun at the center :)
they move by gravity or many other things.
it makes it easier to move objects (usually heavy, large, hard to move, etc) to an area with a higher elevation
The way that the objects are broken up into pieces.
What do objects snap to when you move them
