Force is a push or pull exerted on an object due to the interaction between two objects. It is a vector quantity that can cause an object to accelerate, decelerate, change direction, or deform. The SI unit of force is the newton.
The perpendicular force exerted by a surface pressing against an object is called normal force. This force is perpendicular to the surface and acts in the opposite direction to the force applied by the object.
When you push against an object, the force you apply is called the applied force. This force is the external force exerted on the object by you pushing against it.
The reaction force equation is: Force Mass x Acceleration. This equation is used to calculate the force exerted by a surface in response to an object pressing against it.
Because your feet are not accelerating, the force exerted by the floor upon your feet must be exactly the same as the force exerted by your feet on the floor. If you are standing, the amount of force exerted by your feet, and thus the amount of force exerted by the floor, is equivalent to your weight.
The action force of walking is the force exerted by the foot pushing against the ground to propel the body forward. This force is equal in magnitude and opposite in direction to the reaction force exerted by the ground pushing back against the foot, allowing us to move forward with each step.

Drag is something that is force exerted. It is a force that is exerted in the opposite direction of movement.
The perpendicular force exerted by a surface pressing against an object is called normal force. This force is perpendicular to the surface and acts in the opposite direction to the force applied by the object.

Strength is the amount of force exerted against a resistance.
Newton's second law of motion states that force is equal to mass times acceleration, or F = ma. So, if a force is exerted on something that has mass, it will accelerate.
Because your feet are not accelerating, the force exerted by the floor upon your feet must be exactly the same as the force exerted by your feet on the floor. If you are standing, the amount of force exerted by your feet, and thus the amount of force exerted by the floor, is equivalent to your weight.
