About Micronewtons
A micronewton (µN) is 10⁻⁶ N - the force scale of satellite microthrusters and MEMS actuators. Ion FEEP microthrusters on CubeSats produce 1-1,000 µN to compensate atmospheric drag at sub-500 km altitudes. Newton's law gives F = Gm₁m₂/r² ≈ 6.674 µN between two 1 kg masses 10 cm apart. Comb-drive electrostatic actuators in lab-on-a-chip devices operate at micronewton forces for cell sorting. AFM cantilevers mapping cell stiffness apply 10-100 µN. Red blood cells deform measurably at ~10-20 µN - an optical tweezers assay used to detect malaria. 1 µN = 10⁻⁶ N.
About Teranewtons
One teranewton (TN) is 10¹² N - the force scale of plate tectonics and planetary dynamics. Mantle convection drags tectonic plates with 10¹³-10¹⁵ N per plate, putting the plate-driving slab-pull force (~10¹³ N) firmly in the TN range. Mid-ocean ridge lithosphere sustains several TN per km of spreading length in tension. The tidal force differential across Earth's diameter from the Sun is ~4 × 10¹⁷ N = 4 × 10⁵ TN. Proposed megastructures (space elevators, orbital rings) would also require teranewton-scale structural capacity. 1 TN = 1,000 GN = 10¹² N ≈ 10¹¹ kgf.
