The 3rd law of motion can be displayed showing
A
a rocket taking off
B
a person flying forward after they hit a rock while skating
C
F=Mass x acceleration
D
None of the above
Explanation: 

Detailed explanation-1: -Launching a rocket relies on Newton’s Third Law of Motion. A rocket engine produces thrust through action and reaction. The engine produces hot exhaust gases which flow out of the back of the engine. In reaction, a thrusting force is produced in the opposite reaction.

Detailed explanation-2: -Newton’s Third Law states that “every action has an equal and opposite reaction". In a rocket, burning fuel creates a push on the front of the rocket pushing it forward. This creates an equal and opposite push on the exhaust gas backwards.

Detailed explanation-3: -If the velocity is not zero, then the object maintains that velocity and travels in a straight line. If a net external force is applied, the velocity changes because of the force. The liftoff of a rocket from the launch pad is a good example of this principle.

Detailed explanation-4: -Newton’s Third Law: Action & Reaction His third law states that for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A.

Detailed explanation-5: -Newton’s third law of motion states that to every action there is an equal and opposite reaction. Similarly, when a rocket moves, it exerts the action force on the gases to expel them backwards which in turn exerts an equal and opposite reaction force to move the rocket forward.
