โ๏ธWhich law states that every body continues to be in its state of rest or uniform motion in a straight line unless an external force acts up on : Newton’s first law of motion

โ๏ธAs per Newton’s second law of motion the rate of change of momentum of a body is directly proportional to the Applied force

โ๏ธWhich law states that for every action there is an equal and opposite reaction : Newton’s first law of motion

โ๏ธInertia can be explained with Newton’s first law of motion

โ๏ธWhich law of motion defining the force: Newton’s first law of motion

โ๏ธWhich law of motion is known as the measure of force : Newton’s second law of motion (F=(mv)/t) or F=ma)

โ๏ธWhich law proves that different masses accelerate to the earth at the same rate but with different forces : Newton’s second law of motion

โ๏ธThe propulsion of rockets and the working of jet engine etc are explained with the help of : Newton’s third law of motion

โ๏ธThe flying of a bird is consequence of Newton’s third law of motion
