When an object is falling, the two main forces acting on it are weight close weightA force that acts on mass, pulling it down, due to gravity. Weight is a force and forces are measured in newtons (N).

Abstract: We demonstrate the joint detection of the radial and angular velocities of tagged moving objects using a harmonic radar with dual interferometric-Doppler measurement modes. The radar ...
