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.

According to newton's first law of motion an object tends to remain at rest or in uniform motion until and unless and external forces acts on it so suppose a dog is sleeping and then suddenly it wakes up and starts walking so it has come into motion without any external force acting on it how
