# QuestionUsing Side Thruster on a missile to create a angular acceleration

#### sahilsaxena

Assume a rocket is standing on the ground with mass = 1000 kg, and near the top of rocket we apply a force of 100 N for say 1 sec,now assume that this is sufficient to tip rocket over/start tipping over. If the rocket is mid air and accelerating at 30 m/s^2, then likewise how much force would be required to tilt it pi/180 rad or change its trajectory by some degree, please neglect the change of mass due to consumption of fuel because the value calculated with this assumption is going to be a a value higher than required, so that is not an issue. Will the force required mid air be the same as the force required on the ground with no acceleration ?

Is the basis of your question whether contact with the ground make any difference to the rotation of the rocket? The rocket will turn anyway but the ground contact provides a pivot which may be different to the one in space?

Is this a trick question ? Regardless of the mass, if the rocket is standing on a dime you can push it over with your pinkie. LOL

On a dime maybe, but rockets are wider than dimes and initially supported. I guess the poster may mean with jets running immediately before lift off?
