Question

Q.3.Why a rocket moves in forward direction on ignition?​

Answer 1

Answer:

The movement of the exhaust gases away from the rocket body pushes the rocket in the forward direction, since the force exerted by the exhaust gas has an equal reaction in the opposite direction. So, if the spacecraft has to turn left, the right-side propellers on the craft need to be ignited.

Answer 2

Answer:

According to the newton 3rd law of motion:

every object has an action or reaction force .

The gases are exausted which are in downward direction exert a pressure on opposite side of it

that is the force is applied on a rocket which helps it to tale off.

Here the the action force is applied by rocket as it release gases . And the reaction force is applied by the gases to the rocket .

Which exert a force on a rocket and the rocket takes off.

Hope it helps you
