Equation of motion in classical mechanics
WebThe total force on the rocket will be equal to the force due to the gas escaping minus the weight of the rocket: The rate of lost mass is negative. The velocity is in the negative direction, so, with the two negative signs the term becomes positive. Use this: Solve: WebEquation ( 8) is an expression of the law of conservation of energy. It says that the sum of kinetic energy, 1/2 mv 2, and potential energy, mgz, at any point during the fall, is equal to the total initial energy, mgz 0, before the fall began.
