How to Find Change in Kinetic Energy
Easy peasy! Just use the formula ΔKE = 1/2 * m * (v_f^2 - v_i^2), where m is mass, v_f is final velocity, and v_i is initial velocity.

Take the kinetic energy at the start and subtract it from the kinetic energy at the end. Voilà, you got your change!
Measure initial and final velocities, plug them into the kinetic energy formula for each state, and subtract. Simple as that!
Just use the formula KE_final - KE_initial. Physics ain't that hard, folks!
