Why objects float or sink when placed on surface of water?
Because of the comparative density. If the objects density is greater than water it will sink, if less then it will float.
Why do some objects decompose faster than others?
Objects decopmpose faster than others because of their: size, weight, pressure, and surface area.
Why all objects above the surface of the earth that are left without support fall down?
because of gravity
In freefall do all objects near Earth's surface have the same acceleration?
Without atmospheric drag, all free falling objects near earth's surface will have the same acceleration. But because of friction with the air (air resistance), the velocity of objects due to that acceleration is limited. The actual velocity is dependent on the surface area of the object relative to its mass. The principle of the parachute is to increase the surface area of a falling object with respect to its mass.
When light bounces off of a shiny surface what is it said to be?
When light bounces of a shiny surface, such as a mirror, this is called specular reflection.(Diffuse reflection is when light bounces of a rough surface, such as a wall. You can tell it's a rough surface because you can't see your reflection.)
Why can you see any objects in mirrors?
Because mirrors have a reflective surface?
What is a star in which light cannot escape because of the immense gravitational pull at its surface called?
It is a black hole - which is not a star.
Objects near the surface of the earth fall because what are by the earth?
Gainnkn kinetic energy
What are objects from which light can not escape because of a gravitational pull at its surface?
A black hole. However, it does not have a surface but an event horizon.
What is The measure of an objects surface?
surface area
Why objects float or sink when placed on surface of water?
Because of the comparative density. If the objects density is greater than water it will sink, if less then it will float.
Why do some objects decompose faster than others?
Objects decopmpose faster than others because of their: size, weight, pressure, and surface area.
What is the force of gravity at that surface of asteroids belt?
The asteroid belt does not have a surface as it is not an objects. It is a loose scattering of objects.
Why all objects above the surface of the earth that are left without support fall down?
because of gravity
What objects does friction stop?
Objects with the most surface area.
In freefall do all objects near Earth's surface have the same acceleration?

What would happen if we were to be on Jupiter's surface?
Jupiter has no definite surface. If you did not have a suitable aircraft you would simply fall into the planet's interior to be crushed by the immense pressure.
