The normal force involved in walking is the force exerted by the ground on the person's feet, which counteracts the force of gravity. There is also a normal force exerted by the person's feet on the ground, which helps maintain balance while walking.
Weight plays a crucial role in walking, as it is the force of gravity acting on the person's body. This force must be counteracted by the normal force in order for the person to maintain balance and move forward while walking.
Pushing is the force exerted by the person's legs on the ground, which propels them forward while walking. This force is necessary for movement and is affected by factors such as leg strength and walking speed.
Friction is the force that resists motion between two surfaces in contact. In the case of walking, friction between the person's feet and the ground helps provide traction and prevent slipping. Too much friction can make walking difficult, while too little friction can lead to slipping and loss of balance.
The forces involved in walking can be affected by various factors such as the person's weight, leg strength, walking speed, surface conditions, and footwear. These factors can alter the normal, weight, push, and friction forces, and can impact the overall efficiency and ease of walking.
