Newton's first law states that “every body at rest or in a uniform motion continues to be in its state until and unless an unbalanced external force is acting on it"

The best example for the 1st law is again as we see in every books the space craft which is actually away from the gravitational pull of the Earth.

Second law:“Rate of change of momentum is directly proportional to the external force acting on it”(F=d(m*v)/dt)

Mainly second law is applicable in daily life, the sand pit which we make for long jump is actually in order to decrease the impact(d(m*v)) by increasing the time.A fielder is actually implementing the law while taking a catch are some examples.

While the third law “Every action has an equal and opposite reaction ”(not always equal)

Here we apply this law while swimming and working Principle of rocket,recoling of gun are other examples. (“karma” more related to third law) Pulley is a device where newton's laws are applicable.
