A light object has less momentum than a heavy object. A light object would stop first.
An opaque object
The sun does not determine the shadow, the object that stops its light does.
It really depends on the size, for normal sized keep it not too light but not too heavy you can tell by doing this : spin your bey if it hits an object and stops spinning in one hit it is too light if it wobbles too much it is too heavy if you get it right it will spin for 1 minute like mine
Opaque is the term used to describe an object or substance that stops all light passing.
The energy to produce the light stops and the light stops.
Shadows are formed when light shines on an opaque (solid) or translucent (partially solid, like a net curtain) object. This object stops the light rays, so a shadow is produced in the shape of the object. For example, if you hold your hand in front of a light, then the light will only be seen in the places where your hand is not blocking it. You will then see a hand shaped shadow.
A moving object stops when its force is used up. The resistance to change its motion is known as inertia.
Sure. You don't even have to be blindfolded. You only have to look away from the display and lighted buttons, and you have no other way of knowing when it starts and stops, except for the feeling when you become temporarily heavy or light.
The Earth's gravity stops the object from floating when at rest.
The object slows down and eventully stops.
An object in motion tends to remain in motion unless an external force stops it, an object moves in a straight line unless some force diverts it; and for every action, there is an equal and opposite reaction. An object in motion tends to remain in motion unless an external force stops it; an object moves in a straight line unless some force diverts it.
Typically the ground.
