According to the theory, the average force Favg, applied to the mass multiplied by the duration the force is applied should equal the mass change in momentum. For each run calculate the change in momentum of the mass using the average force, then find the % difference between that and change in momentum using the change in velocity.

The change in momentum for average force is: ΔΔt and it is calculated below.

For thick and thin spring, the %difference between change in momentum for average force and change in momentum for velocities is; 178.27% and 159.72% respectively
