Earth exerts a downward (towards the ground or Earth) force on your body. At the same time, your body exerts an upward (towards your body) force on the Earth. Your body is the one that seems to move, however, because the mass of your body is so much less than the mass of the Earth.
When standing on the ground, the Earth exerts a force equal to your weight in the downward direction (gravitational force) and you exert an equal force in the upward direction on the Earth (reaction force) as per Newton's Third Law of Motion.
The reaction force to the downward push of Billy's weight on the chair is the upward force of the chair pushing back on him. The downward force of Billy's weight on Earth is countered by the upward force of gravity acting on him.
Down ward force is greater than upward force because everything on earth, obeys the laws of gravity, and for a rocket to take off from earth it needs more energy in other to fight the earths gravitational force but despite fighting the gravitational force it still doesnt take off with a full speed, But for a body of mass to fall from the atmosphere its falls with a great speed due to the force of the earths gravity.
Yes, according to Newton's third law of motion, for every action, there is an equal and opposite reaction. So, when you push downward on the Earth to make a pole vault, the Earth exerts an equal force upward on the pole.
If the upward force acting on an object is greater than the downward force (its weight or force of gravity), the object will experience a net upward force causing it to accelerate in the upward direction. This could lead to the object moving upwards, overcoming the force of gravity pulling it downward.

No, gravity is a downward force.
downward
If the upward force acting on an object is greater than the downward force (its weight or force of gravity), the object will experience a net upward force causing it to accelerate in the upward direction. This could lead to the object moving upwards, overcoming the force of gravity pulling it downward.
Buoyant force is an upward force that fluids exert on any object placed in them. It is equal to the weight of the fluid that the object displaces.
Normal Force
The climber must work against gravity as he climbs. Gravity is pulling him downward and he needs to exert force to push himself upward against it.
When you jump, you exert a force greater than the force of gravity to achieve a net positive upward acceleration - at least until your feet leave the ground and you quit exerting force. The net upward force is Fnet = (force you push off with) - (force of gravity) Because the moon has less mass than the earth, the force of gravity is less. As a result, the force you exert to jump on earth would give a higher net upward acceleration on the moon and allow you jump higher.
