## Stopping Power Formula

The following formula is used to calculate the Stopping Power.

**Ps = KE / T**

- Where Ps is the Stopping Power (watts)
- KE is the total kinetic energy (J)
- T is the stopping time (s)

## How to Calculate Stopping Power?

The following two example problems outline how to calculate the Stopping Power.

**Example Problem #1:**

- First, determine the total kinetic energy (J). In this example, the total kinetic energy (J) is measured to be 534.
- Next, determine the stopping time (s). For this problem, the stopping time (s) is calculated to be 4.
- Finally, calculate the Stopping Power using the formula above:

Ps = KE / T

Inserting the values from above and solving the equation with the imputed values gives:

Ps = 534 / 4 = 133.5 (watts)

**Example Problem #2: **

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

total kinetic energy (J) = 5000

stopping time (s) = 10

Entering these values into the formula or calculator above gives us::

Ps = 5000 / 10 = 500 (watts)
