What else can I help you with?
When you are standing on ground how much upward force exerted on you why does this force not lift u up?
The upward force exerted on you while standing on the ground is equal to your weight, as determined by the force of gravity pulling you toward the Earth. This force does not lift you up because it is balanced by the force exerted by the ground pushing back on you (normal force), keeping you in equilibrium and preventing you from accelerating upward.
What is the gravitational force exerted by earth?
The gravitational force exerted by Earth on an object is approximately 9.81 meters per second squared (m/s^2). This force is what gives weight to objects on Earth and causes objects to fall towards the ground when dropped.
Why do objects fall to the ground when thrown upward?
Objects fall back to the ground when thrown upward due to the force of gravity acting upon them. Gravity is a force that pulls objects towards the center of the Earth, causing them to accelerate downwards. When an object is thrown up, it loses its upward velocity and gravity then pulls it back towards the ground.
Why do things thrown upward fall back to the ground?
Things thrown upward fall back to the ground due to the force of gravity, which pulls objects towards the Earth's center. As the object rises, its speed decreases until the pull of gravity overcomes the upward force and causes it to fall back down.
What are the forces acting on a football resting?
-- the gravitational attraction between the football and the Earth, acting vertically downward; -- the normal force of the ground or the shelf under the football, acting vertically upward. These two forces are precisely equal and opposite. If they're weren't, then the football would be accelerating vertically, not at rest.

Can non contact forces be exerted while objects are in contact?
Of course. You and the Earth are mutually attracted by gravitational forces even when you're standing on the ground.
What two forces act on you while your in a moving elevator?
1). gravitational attraction between you and the earth 2). upward "normal" force exerted by the floor on the bottom of your feet These are the same forces that act on you while you're standing on anything, whether it's moving or not.
When you jump on the ground the earth exerts a greater force back up on because it is so massive?
The force that you exert on the Earth is equal to the force that the Earth exerts on you; for every action there is an equal and opposite reaction, so says Newton. What is different is the amount of motion that results. You move, and the Earth (apparently) does not. Actually the Earth is moving all the time, in its orbit around the sun and by rotating on its axis, but it does not noticeably move because you jump on the ground. And that is indeed because it is much more massive than you are. False.
Why does not this force lift you the earth upward?
The upward force balances exactly you weight so the resultant force is zero and you stay on the ground, fortunately!
What is the gravitational force exerted by earth?
The gravitational force exerted by Earth on an object is approximately 9.81 meters per second squared (m/s^2). This force is what gives weight to objects on Earth and causes objects to fall towards the ground when dropped.
When we stand on earth we see the moon upward and when we stand on moon we see the earth upward. Why is that so?
The human body is made to relate to gravity. When standing on a body of mass, whether it is the Earth or the Moon, we will automatically look up to the sky. Our internal balance and the brain make the association.
Why do objects fall to the ground when thrown upward?
Objects fall back to the ground when thrown upward due to the force of gravity acting upon them. Gravity is a force that pulls objects towards the center of the Earth, causing them to accelerate downwards. When an object is thrown up, it loses its upward velocity and gravity then pulls it back towards the ground.
What lies under the north pole ice?
Earth ground the one your standing on now
Is it possible to stand on the crust?
Whenever you set foot on the bare ground of the Earth, you are standing on the crust.
Why do things thrown upward fall back to the ground?
Things thrown upward fall back to the ground due to the force of gravity, which pulls objects towards the Earth's center. As the object rises, its speed decreases until the pull of gravity overcomes the upward force and causes it to fall back down.
