Why do objects fall to the ground when thrown upward?
Objects fall to the ground because of the force of gravity.
Why do falling objects move faster than objects going upward?
Because gravity always tried to pull objects towards the centre of the earth !
How can a tornado pick up something?
Air in a tornado moves upward rapidly, sometimes taking objects with it.
What is the value of g in upward direction?
Since gravity causes objects to fall downward, rather than upward, I would describe the upward force of g, at the surface of the Earth, as -9.8 meters/second2.
Is the upward force that opposes the force of gravity?
Lift is the upward force that opposes the force of gravity.
Why do objects fall to the ground when thrown upward?
Objects fall to the ground because of the force of gravity.
How can kinetic energy convert to potential energy?
By raising objects against gravity (upward)

How can tornadoes pick stuff up?
Air in a tornado moves upward pretty rapidly. This upward moving wind often carries objects with it.

Since gravity causes objects to fall downward, rather than upward, I would describe the upward force of g, at the surface of the Earth, as -9.8 meters/second2.
What makes objects moves?
they move by gravity or many other things.
When will objects thrown upward start to go down?
When the vertical component of their velocity has dwindled to zero because of the acceleration of gravity.
Is it possible for earth to fall?
no. gravity causes objects to fall. So unless the sun(earth's source of gravity) moves, then earth will not "drop"
Does a tornado have gravity?
Gravity is present in a tornado, however, for objects that are not too heavy the upward flow of air in a tornado can overpower gravity. Tornadoes are dependent on convection, which requires gravity, but tornadoes themselves are a thermodynamic rather than gravitational event.
Is the upward force that opposes the force of gravity?
Lift is the upward force that opposes the force of gravity.
How can you explore space if gravity attracts objects toward earth?
The same way you walk up a flight of stairs while gravity attracts you toward earth ... you apply an upward force to the object that's greater than the downward force of gravity. When you do that, the net force on the object is upward, and it accelerates away from the earth.
