Explanation:
F (Newton)= m (kg) * g (m/s^2) The units in this expression are fine, because the by definition 1 N = 1 kg m/s^2. So, if you take a mass of 1 kg, and lift it vertically with your arm, then your arm will be pulling the mass with a force of F = 1 kg * 9.8 m/s^2 = 9.8 N.
A streamlined body is a shape that decreases the friction drag between a fluid, such as air and water, and an object that passes through that fluid. Drag is the force which reduces the speed of the motion.
