# Stopping Power Calculator

## About Stopping Power Calculator (Formula)

The Stopping Power Calculator is a tool used to determine the stopping power of a particle based on its total kinetic energy and stopping time. It is commonly employed in fields such as physics and radiation science to assess the ability of a material or medium to slow down or stop the motion of particles.

The stopping power is calculated using the following formula:

Stopping Power (Ps) = Total Kinetic Energy (KE) / Stopping Time (T)

To calculate the stopping power, the total kinetic energy of the particle is divided by the stopping time. The total kinetic energy represents the energy possessed by the particle due to its motion. The stopping time is the duration in which the particle is decelerated or brought to a halt.

The stopping power is typically expressed in watts, which is a unit of power. It represents the rate at which the particle’s energy is dissipated or absorbed during the stopping process. A higher stopping power indicates a more efficient transfer of energy from the particle to the medium, resulting in faster deceleration or greater energy absorption.

For example, if a particle has a total kinetic energy of 100 joules and it takes 5 seconds to come to a stop, the stopping power would be calculated as follows:

Stopping Power = 100 joules / 5 seconds = 20 watts

This indicates that the particle is dissipating energy at a rate of 20 watts during the stopping process.

The Stopping Power Calculator provides a convenient way to compute the stopping power by entering the values of the total kinetic energy and stopping time. It enables researchers, scientists, and professionals to evaluate the effectiveness of different materials or media in stopping particles and make informed decisions regarding radiation shielding, particle accelerators, and other applications where stopping power is a crucial factor.

By utilizing the Stopping Power Calculator, one can gain insights into the energy transfer dynamics between particles and the stopping medium, contributing to the development of safer and more efficient systems in various scientific and technological fields.
