A 10kg brick and a 1kg book are dropped in a vacuum the force of gravity on the 10-kg brick is?
If this is being conducted in Earth's gravity well, then 32 feet per second per second will be the rate of acceleration towards the surface. It won't stay vacuum for long, though.
What object falls faster a heavy object or a light object in a vacuum?
They both fall at the same rate. This is because they are both only acted upon by one force in the vacuum- gravitational acceleration. The mass, size or shape of the object do not influence the object's motion in a vacuum.
Is gravity an instantaneous force?
No. In Newtonian physics, gravity is treated as an instantaneous force, but in General Relativity, gravity propagates at the speed of light in a vacuum. There's some debate on whether it's actually been experimentally shown that the "speed of gravity" is the same as the speed of light in a vacuum or not. However, there is fairly clear experimental evidence that it does have a speed and is not instantaneous. See the Wikipedia article in "Related Links" for a much longer and more detailed discussion.
What increases As an object falls freely in a vacuum?
the object's falling speed
Does a hot object lose heat in a vacuum?
NO
Does an object dropped from twice as high take twice the time to fall?
No. Objects falling on Earth in a vacuum fall at an increasing speed of 32 feet per second per second and the same object dropped from the higher level will be traveling faster during the second half of its fall, thereby it will take less than twice the time required to fall half the distance.
What will drop first a big ball or a small ball?
Both will reach the ground at the same time if they were dropped at the same time in a vacuum. This is a well proven fact that the mass has no effect on the acceleration of an object in a free fall in a vacuum.
Where can I buy a backpack vacuum from?
You can buy a backpack vacuum from Amazon they have several listed.

In a vacuum does an object have buoyant force?
No.

Which will fall faster a feather or ping pong ball if dropped in a vacuum?
Both will fall at the same time in vacuum because there is no resistance.
Does a hot object lose heat in a vacuum?
NO
Does mass determine the acceleration due to gravity?
The acceleration due to Gravity is constant at 32 feet per second per second, if you dropped a feather and a cannon ball in a vacuum they would fall at the same rate and hit the floor at he same time.
What is the speed of light in miles per second in a vacuum?
The speed of light is 186,000 miles per second in a vacuum.
