Calculate Initial Kinetic Energy (KEi)





Formula

The formula to calculate the Initial Kinetic Energy (KEi) is:

\[ KEi = KEf - \frac{1}{2} \times dm \times dV^2 \]

What is Initial Kinetic Energy?

Initial Kinetic Energy (KEi) is the energy possessed by an object due to its motion at the start of a given period. It is calculated using the final kinetic energy, the change in mass, and the change in velocity. The most common units for Initial Kinetic Energy are Joules.

Example

Let's say the final kinetic energy (KEf) is 500 Joules, the change in mass (dm) is 10 kg, and the change in velocity (dV) is 2 m/s. Using the formula:

\[ KEi = 500 - \frac{1}{2} \times 10 \times 2^2 = 500 - 20 = 480 \text{ Joules} \]

So, the Initial Kinetic Energy (KEi) is 480 Joules.
