The fact that we stand on the surface of the Earth - rather than falling right through to the center of the Earth - indicates that there is. The two forces - the Earth's surface pushing us upward, and Earth's gravity pulling us downward - cancel in this case.
In the above, the forces cancel out -- we are pulled down, but the floor pushes up at the same force (different direction. But is there a force that cancels out gravity? The best I can think of is an Earth above and an Earth below, so that the two opposite directed forces cancel out. Although in orbiting, the centrifugal force cancels (equal and opposite) of gravity.

Why does mass not affect the period of a pendulum?
The period of a pendulum is determined by the length of the pendulum and the acceleration due to gravity, but it is independent of the mass of the pendulum bob. This is because as the mass increases, so does the force of gravity acting on it, resulting in a larger inertia that cancels out the effect of the increased force.
How does upthrust depend on accleration due to gravity?
it depends on acceleration due to gravity as f=mg, when acceleration due to gravity increases the force acting also increases.when force acting increases it cancels the upward thrust(buoyant force)so the body sinks in the liquid.
Why does gravity decreases with increase in depth?
The force of gravity inside a hollow shell is zero, according to an elegant theorem by Isaac Newton. Therefore at depth the force of gravity comes only from the sphere which has its radius equal to your distance from the centre.
Why you feel weightless in lift?
You feel weightless in a lift because the lift and everything inside it, including you, are accelerating downward at the same rate. This acceleration cancels out the force of gravity acting on you, making you feel weightless.
What is the net force of your science book resting on your desk?
forces acting on the book when it rests in your hands are: gravity, the equal and opposite force exerted by your hand on the book (in opposition to force of gravity). Also, air pressure, but its from all sides so it cancels itself out.
What is it when a falling object stops accelerating?
terminal velocity, or free fall, as the air drag cancels gravity force and stops aacceleration
Does the force of gravity on an object differ from above and below water?
No. The mutual forces of gravity between the Earth and an object are exactly the same when the object is underwater as they are when it's above water. But when the object is underwater, there's an upward buoyant force on it, which compensates and cancels some or all of the gravitational force.

What is a force on an object that cancels all other forces?
The equilibriant.
What is it called when a falling objects stops accelerating?
it stops accelerating at terminal velocity due to the air

Why do you seem to weigh more in air than you in water?
There is a buoyant force in water that largely counteracts gravity. Since the human body is about the same density as water, buoyancy just about completely cancels out the force you feel from gravity, effectively rendering you almost weightless. Since air is so much less dense than water the buoyant force you experience is negligible.

What is the gravity at the center of the earth?
Zero. The gravitation from pieces of Earth in different directions cancels in this case.
