Question

Show the newtons second law of motion in the real law of motion

Answer 1

Proof. When we can show that Newton’s first and third law are contained in the second law, then we can say that it is the real law of motion.
(i) First law is contained in second law: According to Newton’s second law of motion,



It means that there will be no acceleration in the body if no external force is applied. This represents that a body at rest will remain at rest and a body in uniform motion will continue to move along the same straight line in the absence of an external force. This corresponds to Newton’s first law of motion. So, first law of motion is contained in Second law of motion






Answer 2

Answer:

imagine

☞Rockets can propel themselves through the nothingness of space because of two fundamental laws of physics: Newton’s Third Law and the Conservation of Linear Momentum.

☞Both ideas are essential to understanding how nearly everything in the universe moves.

☞When an ice skater takes off from a dead stop, she digs her blade into the ice and the ice pushes back with an equal and opposite force, sending her gliding across the rink.

☞When a cannon is fired, the cannonball goes hurtling through the air while the cannon recoils backward in response.

☞Both of these principles stem from the same general idea: that the universe likes to keep everything in balance.
