WebJul 21, 2024 · Thrust is a mechanical force, so the propulsion system must be in physical contact with a working fluid to produce thrust. Thrust is generated most often through the reaction of accelerating a mass of gas. Since thrust is a force, it is a vector quantity having both a magnitude and a direction. WebIt can be calculated using the equation acceleration = resultant force ( newtons, N) divided by mass (kilograms, kg). One model rocket has a mass of 50 grams and a rocket engine that produces a thrust of 5 N for 1 second. To find the weight, 50 g needs to be changed into kilograms by dividing by 1000. This gives a mass of 0.050 kg.
