A study, from researchers at Imperial College London, attempts to quantify the force of kicks exerted whilst in the womb. MRI scans were used and algorithms to determine exerted force.

This forces exerted went from about 2.95kgs (29 Newtons) of force at 20 weeks to 4.76Kgs (47 Newtons) at 30 weeks. But by 35 weeks, the strength of the fetal kicks had decreased to 1.7 Kgs
