Question

How do jogging on soft ground and wearing padded shoes reduce the pressures to which the feet and legs are subjected?

Short answer

Since changing the runner's momentum takes longer on a softer surface.

Step-by-step solution

Conceptual Introduction

Fluid statics, often known as hydrostatics, is a branch of fluid mechanics that investigates the state of balance of a floating and submerged body, as well as the pressure in a fluid, or imposed by a fluid, on an immersed body.

Defining impulsive force

A padded shoe has an advantage over a normal shoe. It reduces impulsive force. An impulsive force is the force acting on an object for a short duration. While using padded shoes, it increases the duration for which the force acts on the body. Since the force and time period are inversely related, less force will be exerted on the feet.

Relating force and pressure

Pressure and force are directly related. Because, pressure is the force acting per unit area. Here, the force decreased, and as a result, the pressure will also decrease. Because of the reduced pressure, it reduces the pain caused to the feet while jogging.

Therefore, the padded shoes reduce pressure on the feet due to their less impulsive force.
