Expert Answer
Newton's First Law of Motion : An object continues to be in a state of rest or in a state of motion untill an external force acts on it.
Example: This is not visually evident in the atmosphere due to friction of the surfaces and the air resistance, but in space, the spaceships or the aircrafts propagate using the same principle, as in outer space, there is no resistance to it's motion.
 
Newton's Second Law: Rate of change of momentum of a body is directly proportional to the amount of force acting on it.
Example : The wicketkeeper in the game of Cricket catches a ball moving in high speed by taking his/her hand backwards to reduce the impact and changes the momentum accordingly.
 
Newton's Third Law of Motion: Every action (force) has an equal (in magnitude) and opposite (in dircetion) reaction (force).
Example: The ignition of a space vehicle from the surface of the Earth.
