To stop the table in your class falling through the floor what must the floor do against the force of gravity pulling the table down?

The floor must exert a force equal to that of the force exerted on the desk from gravity. This force is called a "normal force"

When the only force affecting an object is gravity that object is in?
Freefall this means the objects is falling through the air while gravity is pulling.
What is the only force affecting an object in gravity that objects is in?
Freefall this means the objects is falling through the air while gravity is pulling.
Can you produce electricity with gravity?
Yes, electricity can be produced from gravity. One popular method is to find a place where gravity is pulling water down, and guide the water through an electrical generator while it's falling. The power that comes out of the generator is then called "hydroelectric" power. A lot of it can be found in places connected to Hoover Dam, Niagara Falls, etc.
What factors affect the rate of object falls through air?
The force of gravity will affect the rate of falling in air. As will the aerodynamic shape of the object. And assuming that the air is not moving with or against the direction of fall.
Does gravity work through water?
Yes. There's no material known that insulates against gravity.
To stop a table falling through the floor in your classroom what must the floor do against the force of the gravity pulling th table down?
Push it up.
When the only force affecting an objects is gravity that objects is in?
Freefall this means the objects is falling through the air while gravity is pulling.
What is the only force affecting an object in gravity that objects is in?
Freefall this means the objects is falling through the air while gravity is pulling.

Freefall this means the objects is falling through the air while gravity is pulling.
What opposing forces act on an object falling freely through the atmosphere?
The forces that affect the rate of a falling object are Gravity and Air Resistance. Gravity affects the speed and the velocity of the object by speeding it up as it falls closer to the earth, and Air resistance works against the object pushing against it.
How Does a Pump work?
A pump works against gravity by pulling water up through a spicet. As you "pump" the handle the air is removed from the line so ultimately in time you are pulling up the water from the reserve.
What are the forces acting on an object falling through the air?
Air resistance and gravity.
Does the size of an object affect the rate at which it falls?
Only if it's falling through air. If it's just the falling object and gravity, then no.
Can you produce electricity with gravity?
Yes, electricity can be produced from gravity. One popular method is to find a place where gravity is pulling water down, and guide the water through an electrical generator while it's falling. The power that comes out of the generator is then called "hydroelectric" power. A lot of it can be found in places connected to Hoover Dam, Niagara Falls, etc.
Can you dig through the Earth's core and escape the central gravity there if you found a way to withstand the heat?
No. You can dig TO the centre. But once you go through, then you will experience gravity pulling in the opposite direction.
What factors affect the rate of object falls through air?
The force of gravity will affect the rate of falling in air. As will the aerodynamic shape of the object. And assuming that the air is not moving with or against the direction of fall.
What is a general force that people encounter daily?
gravity, the one that keeps you falling down. or the electromagnetic force which keeps you from falling through the floor.
