Lift
In mechanics, the force exerted upwards by the surface that a body sits on is equal and opposite to the force exerted downwards by that body and is referred to as the Ground Reaction Force (GRF) or simply Reaction.

Welll...... when you jump... you leave the ground... when you walk.... you dont.... unless your klumsy.... or if youre jump walking....
In order to walk from 15 below ground to 45 above ground, you have to climb a total of 60 floors.
The force of gravity enables us to walk on Earth by pulling us towards the ground. Gravity is the force of attraction between objects with mass, like us and the Earth. This force keeps us grounded and prevents us from floating off into space.
Frictional force provides the necessary traction between our feet and the ground to prevent slipping when we walk. When we push off the ground with our feet, the friction between our shoes and the ground helps propel us forward. Without friction, our feet would not be able to grip the ground effectively, making walking difficult or even impossible.
The action force is the force exerted by your feet on the ground. This force is the force that you apply to the ground when walking.
The force that allows you to walk is friction between the soles of your shoes and the ground. When you push back on the ground with your foot, the friction prevents your foot from slipping, allowing you to move forward.
When you walk, you push the ground backward with the same force that the ground pushes you forward. This is an example of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. So, the force you apply on the ground causes it to push back on you with the same force, allowing you to move forward.
When you begin to walk forward, the force exerted by your leg muscles on the ground generates a reaction force that propels you forward. This force pushes against the ground, causing your body to accelerate in the direction you are walking.
Friction between your shoes and the ground is the force that keeps your feet from sliding as you walk. The rough texture of your shoe sole and the ground surface creates resistance against sliding motion.
When you walk, the force of friction between your feet and the ground propels you forward. As you push off with one foot, the friction from the ground resists your movement, causing you to move in the opposite direction. This process of push and resistance allows you to walk.
When you walk, you use the force of friction between your feet/shoes and the ground to propel yourself forward. Your muscles also generate the force needed to lift and move your legs.
Friction between our feet and the ground prevents slipping by providing traction. The frictional force resists the relative motion between our feet and the ground, allowing us to push off and move forward with each step. This gripping effect enables us to walk securely without slipping, even without wearing slippers.
The force of gravity pulls the man toward the ground, creating contact between his feet and the surface. This contact provides the friction needed to push off and move forward while walking.
The net force that enables an object to accelerate is a force greater than zero.
